The Record
Having said Morning Prayer, we left at 9.30A. M., after a night in which all of us slept soundly—the first sound sleep some had enjoyed for a long time. Contentment and satisfaction are great somnifacients. The Grand Basin was glorious in sunshine, the peaks crystal-clear against a cloudless sky, the huge blocks of ice thrown down by the earthquake and scattered all over the glacier gleamed white in the sunshine, deep-blue in the shadow. We wound our way downward, passing camp site after camp site, until at the first place we camped in the Grand Basin we stopped for lunch. Then we made the traverse under the cliffs to the Parker Pass, which we reached at 1.30P. M.The sun was hot; there was not a breath of wind; we were exceedingly thirsty and we decided to light the primus stove and make a big pot of tea and replenish the thermos bottles before attempting the descent of the ridge. While this was doing a place was found to cache the minimum thermometer and a tin can that had held a photographic film, in which we had placed a record of our ascent. Above, we had not found any distinctive place in which a record could be deposited with the assurance that it would be found by any one seeking it. One feels sure that in the depth of winter very great coldmust occur even at this elevation. Yet we should have liked to leave it much higher. Without some means, which we did not possess, of marking a position, there would, however, have been little use in leaving it amid the boulders where we hunted unsuccessfully for Professor Parker’s instrument. We had hoped to be able to grave some sign upon the rocks with the geological hammer, but the first time it was brought down upon the granite its point splintered in the same exasperating way that the New York dealer’s fancy ice-axes behaved when it was attempted to put them to practical use. “Warranted cast steel” upon an implement ought to be a warning not to purchase it for mountain work. Tool-steel alone will serve.
Our little record cache at the Parker Pass, placed at the foot of the west or upward-facing side of the great slab which marks the natural camping site, should stand there for many years. It is not a place where snow lies deep or long, and it will surely be found by any who seek it. We took our last looks up into the Grand Basin, still brilliant in the sunshine, our last looks at the summit, still cloudless and clear. There was a melancholy even in the midst of triumph in looking for the last time at these scenes where we hadso greatly hoped and endeavored—and had been so amply rewarded. We recalled the eager expectation with which we first gazed up between these granite slabs into the long-hidden basin, a week before, and there was sadness in the feeling that in all probability we should never have this noble view again.
Harper Glacier
Before the reader turns his back upon the Grand Basin once for all, I should like to put a name upon the glacier it contains—since it is the fashion to name glaciers. I should like to call it the Harper Glacier, after my half-breed companion of three years, who was the first human being to reach the summit of the mountain. This reason might suffice, but there is another and most interesting reason for associating the name Harper with this mountain. Arthur Harper, Walter’s father, the pioneer of all Alaskan miners, “the first man who thought of trying the Yukon as a mining field so far as we know,” as William Ogilvie tells us in his “Early Days on the Yukon”[5](and none had better opportunity of knowing than Ogilvie), was also the first man to make written reference to this mountain, since Vancouver, the great navigator, saw it from the head of Cook’s Inlet in 1794.
Arthur Harper, in company with Al. Mayo, made the earliest exploration of the Tanana River, ascending that stream in the summer of 1878 to about the present site of Fairbanks; and in a letter to E. W. Nelson, of the United States Biological Survey, then on the Alaskan coast, Harper wrote the following winter of the “great ice mountain to the south” as one of the most wonderful sights of the trip.[6]It is pleasant to think that a son of his, yet unborn, was to be the first to set foot on its top; pleasantly also the office of setting his name upon the lofty glacier, the gleam from which caught his eye and roused his wonder thirty years ago, falls upon one who has been glad and proud to take, in some measure, his place.
Descent
Then began the difficulty and the danger, the toil and the anxiety, of the descent of the ridge. Karstens led, then followed Tatum, then the writer, and then Walter. The unbroken surface of the ridge above the cleavage is sensationally steep, and during our absence nearly two feet of new snow had fallen upon it. The steps that had been shovelled as we ascended were entirely obliterated and it was necessary to shovel new ones; it was the very heat of the day, and by thecanons of climbing we should have camped at the Pass and descended in the early morning. But all were eager to get down, and we ventured it. Now that our task was accomplished, our minds reverted to the boy at the base camp long anxiously expecting us, and we thought of him and spoke of him continually and speculated how he had fared. One feels upon reflection that we took more risk in descending that ridge than we took at any time in the ascent. But Karstens was most cautious and careful, and in the long and intensive apprenticeship of this expedition had become most expert. I sometimes wondered whether Swiss guides would have much to teach either him or Walter in snow-craft; their chief instruction would probably be along the line of taking more chances, wisely. If the writer had to ascend this mountain again he would intrust himself to Karstens and Walter rather than to any Swiss guides he has known, for ice and snow in Alaska are not quite the same as ice and snow in the Alps or the Canadian Rockies.

The loose snow was shovelled away and the steps dug in the hard snow beneath, and the creepers upon our feet gave good grip in it. Thus, slowly, step by step, we descended the ridge and in an hour and a half had reached the cleavage,the most critical place in the whole descent. With the least possible motion of the feet, setting them exactly in the shovelled steps, we crept like cats across this slope, thrusting the points of our axes into the holes that had been made in the ice-wall above, moving all together, the rope always taut, no one speaking a word. When once Karstens was anchored on the further ice he stood and gathered up the rope as first one and then another passed safely to him and anchored himself beside him, until at last we were all across. Then, stooping to pass the overhanging ice-cliff that here also disputed the pack upon one’s back, we went down to the long, long stretch of jagged pinnacles and bergs, and our intricate staircase in the masonry of them. Shovelling was necessary all the way down, but the steps were there, needing only to be uncovered. Passing our ridge camp, passing the danger of the great gable, down the rocks by which we reached the ridge and down the slopes to the glacier floor we went, reaching our old camp at 9.30P. M., six and a quarter hours from the Parker Pass, twelve hours from the eighteen-thousand-foot camp in the Grand Basin, our hearts full of thankfulness that the terrible ridge was behind us. Until we reached the glacier floor the weather had beenclear; almost immediately thereafter the old familiar cloud smother began to pour down from above and we saw the heights no more.
The Glacier Camp
The camp was in pretty bad shape. The snow that had fallen upon it had melted and frozen to ice, in the sun’s rays and the night frosts, and weighed the tent down to the ground. But an hour’s work made it habitable again, and we gleefully piled the stove with the last of our wood and used the last spoonfuls of a can of baking-powder to make a batch of biscuits, the first bread we had eaten in two weeks.
Next day we abandoned the camp, leaving all standing, and, putting our packs upon a Yukon sled, rejecting the ice-creepers, and resuming our rough-locked snow-shoes, we started down the glacier in soft, cloudy weather to our base camp. Again it had been wiser to have waited till night, that the snow bridges over the crevasses might be at their hardest; but we could not wait. Every mind was occupied with Johnny. We were two weeks overstayed of the time we had told him to expect our return, and we knew not what might have happened to the boy. The four of us on one rope, Karstens leading and Walter at the gee-pole, we went down the first sharp descents of the glaciers without much trouble, the new, soft snowmaking a good brake for the sled. But lower down the crevasses began to give us trouble. The snow bridges were melted at their edges, and sometimes the sled had to be lowered down to the portion that still held and hauled up at the other side. Sometimes a bridge gave way as its edge was cautiously ventured upon with the snow-shoes, and we had to go far over to the glacier wall to get round the crevasse. The willows with which we had staked the trail still stood, sometimes just their tips appearing above the new snow, and they were a good guide, though we often had to leave the old trail. At last the crevasses were all passed and we reached the lower portion of the glacier, which is free of them. Then the snow grew softer and softer, and our moccasined feet were soon wet through. Large patches of the black shale with which much of this glacier is covered were quite bare of snow, and the sled had to be hauled laboriously across them. Then we began to encounter pools of water, which at first we avoided, but they soon grew so numerous that we went right through them.
Flowers
The going grew steadily wetter and rougher and more disagreeable. The lower stretch of a glacier is an unhandsome sight in summer: all sorts of rock débris and ugly black shale, with discoloredmelting ice and snow, intersected everywhere with streams of dirty water—this was what it had degenerated into as we reached the pass. The snow was entirely gone from the pass, so the sled was abandoned—left standing upright, with its gee-pole sticking in the air that if any one else ever chanced to want it it might readily be found. The snow-shoes were piled around it, and we resumed our packs and climbed up to the pass. The first thing that struck our eyes as we stood upon the rocks of the pass was a brilliant trailing purple moss flower of such gorgeous color that we all exclaimed at its beauty and wondered how it grew clinging to bare rock. It was the first bright color that we had seen for so long that it gave unqualified pleasure to us all and was a foretaste of the enhancing delights that awaited us as we descended to the bespangled valley. If a man would know to the utmost the charm of flowers, let him exile himself among the snows of a lofty mountain during fifty days of spring and come down into the first full flush of summer. We could scarcely pass a flower by, and presently had our hands full of blooms like schoolgirls on a picnic.
But although the first things that attracted our attention were the flowers, the next were the mosquitoes. They were waiting for us at the passand they gave us their warmest welcome. The writer took sharp blame to himself that, organizing and equipping this expedition, he had made no provision against these intolerable pests. But we had so confidently expected to come out a month earlier, before the time of mosquitoes arrived, that although the matter was suggested and discussed it was put aside as unnecessary. Now there was the prospect of a fifty or sixty mile tramp across country, subject all the while to the assaults of venomous insects, which are a greater hindrance to summer travel in Alaska than any extremity of cold is to winter travel.
Not even the mosquitoes, however, took our minds from Johnny, and a load was lifted from every heart when we came near enough to our camp to see that some one was moving about it. A shout brought him running, and he never stopped until he had met us and had taken the pack from my shoulders and put it on his own. Our happiness was now unalloyed; the last anxiety was removed. The dogs gave us most jubilant welcome and were fat and well favored.
Johnny and the Sugar
What a change had come over the place! All the snow was gone from the hills; the stream that gathered its three forks at this point roared over its rocks; the stunted willows were in full leaf; thethick, soft moss of every dark shade of green and yellow and red made a foil for innumerable brilliant flowers. The fat, gray conies chirped at us from the rocks; the ground-squirrels, greatly multiplied since the wholesale destruction of foxes, kept the dogs unavailingly chasing hither and thither whenever they were loose. We never grew tired of walking up and down and to and fro about the camp—it was a delight to tread upon the moss-covered earth after so long treading upon nothing but ice and snow; it was a delight to gaze out through naked eyes after all those weeks in which we had not dared even for a few moments to lay aside the yellow glasses in the open air; it was a delight to see joyful, eager animal life around us after our sojourn in regions dead. Supper was a delight. Johnny had killed four mountain-sheep and a caribou while we were gone, and not only had fed the dogs well, but from time to time had put aside choice portions expecting our return. But what was most grateful to us and most extraordinary in him, the boy had saved, untouched, the small ration of sugar and milk left for his consumption, knowing that ours was all destroyed; and we enjoyed coffee with these luxurious appurtenances as only they can who have been long deprived of them. There are notmany boys of fifteen or sixteen of any race who would voluntarily have done the like.

The next day there was much to do. There were pack-saddles of canvas to make for the dogs’ backs that they might help us carry our necessary stuff out; our own clothing and footwear to overhaul, bread to bake, guns to clean and oil against rust. Yet withal, we took it lazily, with five to divide these tasks, and napped and lay around and continually consumed biscuits and coffee which Johnny continually cooked. We all took at least a partial bath in the creek, cold as it was, the first bath in—well, in a long time. Mountain climbers belong legitimately to the great unwashed.
It was a day of perfect rest and contentment with hearts full of gratitude. Not a single mishap had occurred to mar the complete success of our undertaking—not an injury of any sort to any one, nor an illness. All five of us were in perfect health. Surely we had reason to be grateful; and surely we were happy in having Him to whom our gratitude might be poured out. What a bald, incomplete, and disconcerting thing it must be to have no one to thank for crowning mercies like these!
On Tuesday, the 10th June, we made our final abandonment, leaving the tent standing with stoveand food and many articles that we did not need cached in it, and with four of the dogs carrying packs and led with chains, packs on our own backs and the ice-axes for staves in our hands, we turned our backs upon the mountain and went down the valley toward the Clearwater. The going was not too bad until we had crossed that stream and climbed the hills to the rolling country between it and the McKinley Fork of the Kantishna. Again and again we looked back for a parting glimpse of the mountain, but we never saw sign of it any more. The foot-hills were clear, the rugged wall of the glacier cut the sky, but the great mountain might have been a thousand miles off for any visible indication it gave. It is easy to understand how travellers across equatorial Africa have passed near the base of the snowy peaks of Ruwenzori without knowing they were even in the neighborhood of great mountains, and have come back and denied their existence.
Across Country
The broken country between the streams was difficult. Underneath was a thick elastic moss in which the foot sank three or four inches at every step and that makes toilsome travelling. The mosquitoes were a constant annoyance. But the abundant bird life upon this open moorland, continually reminding one as it did of moorlands inthe north of England or of Scotland, was full of interest. Ptarmigan, half changed from their snowy plumage to the brown of summer, and presenting a curious piebald appearance, were there in great numbers, cackling their guttural cry with its concluding notes closely resembling the “ko-ax, ko-ax” of the Frogs’ Chorus in the comedy of Aristophanes; snipe whistled and curlews whirled all about us. Half-way across to the McKinley Fork it began to rain, thunder-peal succeeding thunder-peal, and each crash announcing a heavier downpour. Soon we were all wet through, and then the rain turned to hail that fell smartly until all the moss was white with it, and that gave place to torrents of rain again. Dog packs and men’s packs were alike wet, and no one of us had a dry stitch on him when we reached the banks of the McKinley Fork and the old spacious hunting tent that stands there in which we were to spend the night. Rather hopelessly we hung our bedding to dry on ropes strung about some trees, and our wet clothing around the stove. By taking turns all the night in sitting up, to keep a fire going, we managed to get our clothes dried by morning, but the bedding was wet as ever. Fortunately, the night was a warm one.
Glacial Streams
The next morning there was the McKinley Forkto cross the first thing, and it was a difficult and disagreeable task. This stream, which drains the Muldrow Glacier and therefore the whole northeast face of Denali, occupies a dreary, desolate bed of boulder and gravel and mud a mile or more wide; rather it does not occupy it, save perhaps after tremendous rain following great heat, but wanders amid it, with a dozen channels of varying depth but uniform blackness, the inky solution of the shale which the mountain discharges so abundantly tingeing not only its waters but the whole Kantishna, into which it flows one hundred miles away. Commonly in the early morning the waters are low, the night frosts checking the melting of the glacier ice; but this morning the drainage of yesterday’s rain-storm had swollen them. Channel after channel was waded in safety until the main stream was reached, and that swept by, thigh-deep, with a rushing black current that had a very evil look. Karstens was scouting ahead, feeling for the shallower places, stemming the hurrying waters till they swept up to his waist. The dogs did not like the look of it and with their packs, still wet from yesterday, were hampered in swimming. Two that Tatum was leading suddenly turned back when half-way across, and the chains, entangling his legs, pulled him over faceforemost into the deepest of the water. His pack impeded his efforts to rise, and the water swept all over him. Karstens hurried back to his rescue, and he was extricated from his predicament, half drowned and his clothes filled with mud and sand. There was no real danger of drowning, but it was a particularly noxious ducking in icy filth. The sun was warm, however, and after basking upon the rocks awhile he was able to proceed, still wet, though he had stripped and wrung out his clothes—for we had no dry change—and very gritty in underwear, but taking no harm whatever. I think Tatum regretted losing, in the mad rush of black water, the ice-axe he had carried to the top of the mountain more than he regretted his wetting.
Birds and Beasts
On the further bank of the McKinley Fork we entered our first wood, a belt about three miles wide that lines the river. Our first forest trees gave us almost as much pleasure as our first flowers. Animal life abounded, all in the especially interesting condition of rearing half-grown young. Squirrels from their nests scolded at our intrusion most vehemently; an owl flew up with such a noisy snapping and chattering that our attention was drawn to the point from which she rose, and there, perched upon a couple of rotten stumps a few feet apart, were two half-fledgedowlets, passive, immovable, which allowed themselves to be photographed and even handled without any indication of life except in their wondering eyes and the circumrotary heads that contained them. Moose signs and bear signs were everywhere; rabbits, now in their summer livery, flitted from bush to bush. That belt of wood was a zoological garden stocked with birds and mammals. And we rejoiced with them over their promising families and harmed none.
From the wood we rose again to the moorland—to the snipe and ptarmigan and curlews, some yet sitting upon belated eggs—to the heavy going of the moss and the yet heavier going of niggerhead. Our journey skirted a large lake picturesquely surrounded by hills, and we spoke of how pleasantly a summer lodge might be placed upon its shores were it not for the mosquitoes. The incessant leaping of fish, the occasional flight of fowl alone disturbed the perfect reflection of cliff and hill in its waters. At times we followed game trails along its margin; at times swampy ground made us seek the hillside.
Thus, slowly covering the miles that we had gone so quickly over upon the ice of the lake two months before, we reached Moose Creek and the miners’ cabins at Eureka late at night and receivedwarm welcome and most hospitable entertainment from Mr. Jack Hamilton. It was good to see men other than our own party again, good to sleep in a bed once more, good to regale ourselves with food long strange to our mouths. Here we had our first intimation of any happenings in the outside world for the past three months and sorrowed that Saint Sophia was still to remain a Mohammedan temple, and that the kindly King of Greece had been murdered. Here also Hamilton generously provided us with spare mosquito-netting for veils, and we found a package of canvas gloves I had ordered from Fairbanks long before, and so were protected from our chief enemies. From Moose Creek we went over the hills to Caribou Creek and again were most kindly welcomed and entertained by Mr. and Mrs. Quigley, and discussed our climb for a long while with McGonogill of the “pioneer” party. Then, mainly down the bed of Glacier Creek, now on lingering ice or snow-drift, with the water rushing underneath, now on the rocks, now through the brush, crossing and recrossing the creek, we reached the long line of desolate, decaying houses known as Glacier City, and found convenient refuge in one of the cabins therein, still maintained as an occasional abode. On theoutskirts of the “city” next morning a moose and two calves sprang up from the brush, our approach over the moss not giving enough notice to awake her from sleep until we were almost upon her.

The Boat
Instead of pursuing our way across the increasingly difficult and swampy country to the place where our boat and supplies lay cached, we turned aside at midday to the “fish camp” on the Bearpaw, and, after enjoying the best our host possessed from the stream and from his early garden, borrowed his boat, choosing twenty miles or so on the water to nine of niggerhead and marsh. But the river was very low and we had much trouble getting the boat over riffles and bars, so that it was late at night when we reached that other habitation of dragons known as Diamond City. While we submerged our cached poling boat to swell its sun-dried seams, Walter and Johnny returned the borrowed boat, and, since the stream had fallen yet more, were many hours in reaching the fish camp and in tramping back.
The Beaver and the Indians
But the labor of the return journey was now done. A canvas stretched over willows made a shelter for the centre of the boat, and at noon on the second day men, dogs, and baggage were embarked, to float down the Bearpaw to theKantishna, to the Tanana, to the Yukon. The Bearpaw swarmed with animal life. Geese and ducks, with their little terrified broods, scooted ahead of us on the water, the mothers presently leaving their young in a nook of the bank and making a flying détour to return to them. Sometimes a duck would simulate a broken wing to lure us away from the little ones. We had no meat and were hungry for the usual early summer diet of water-fowl, but not hungry enough to kill these birds. Beaver dropped noisily into the water from trees that exhibited their marvellous carpentry, some lying prostrate, some half chiselled through. It seemed, indeed, as though the beaver were preparing great irrigation works all through this country. Since the law went into effect prohibiting their capture until 1915 they have increased and multiplied all over interior Alaska. They are still caught by the natives, but since their skins cannot be sold the Indians are wearing beaver garments again to the great advantage of health in the severe winters. One wishes very heartily that the prohibition might be made perpetual, for only so will fur become the native wear again. It is good to see the children, particularly, in beaver coats and breeches instead of the wretched cotton that otherwise is almosttheir only garb. Would it be altogether beyond reason to hope that a measure which was enacted to prevent the extermination of an animal might be perpetuated on behalf of the survival of an interesting and deserving race of human beings now sorely threatened? Or is it solely the conservation of commercial resources that engages the attention of government? There are few measures that would redound more to the physical benefit of the Alaskan Indian than the perpetuating of the law against the sale of beaver skins. With the present high and continually appreciating price of skins, none of the common people of the land, white or native, can afford to wear furs. Such a prohibition as has been suggested would restore to Alaskans a small share in the resources of Alaska. Is there any country in the world where furs are actually needed more?
Not only beaver, but nearly all fur and game animals have greatly increased in the Kantishna country. In the year of the stampede, when thousands of men spent the winter here, there was wholesale destruction of game and trapping of fur. But the country, left to itself, is now restocked of game and fur, except of foxes, the high price of which has almost exterminated them here and is rapidly exterminating them throughoutinterior Alaska. They have been poisoned in the most reckless and unscrupulous way, and there seems no means of stopping it under the present law. We saw scarcely a fox track in the country, though a few years ago they were exceedingly plentiful all over the foot-hills of the great range. Mink, marten, and muskrat were seen from time to time swimming in the river; a couple of yearling moose started from the bank where they had been drinking as we noiselessly turned a bend; brilliant kingfishers flitted across the water. So down these rivers we drifted, sometimes in sunshine, sometimes in rain, until early in the morning of the 20th June, we reached Tanana, and our journey was concluded three months and four days after it was begun. When the telegraph office opened at 8 o’clock a message was sent, in accordance with promise, to a Seattle paper, and it illustrates the rapidity with which news is spread to-day that a ship in Bering Sea, approaching Nome, received the news from Seattle by wireless telegraph before 11A. M.But a message from the Seattle paper received the same morning asking for “five hundred more words describing narrow escapes” was left unanswered, for, thank God, there were none to describe.
The determination of the heights of mountains by triangulation is, of course, the method that in general commends itself to the topographer, though it may be questioned whether the very general use of aneroids for barometric determinations has not thrown this latter means of measuring altitudes into undeserved discredit when the mercurial barometer is used instead of its convenient but unreliable substitute.
The altitude given on the present maps for Denali is the mean of determinations made by triangulation by three different men: Muldrow on the Sushitna[7]side in 1898, Raeburn on the Kuskokwim side in 1902, and Porter, from the Yentnacountry in 1906. In addition, a determination was made by the Coast and Geodetic Survey in 1910, from points near Cook’s Inlet. “The work of the Coast Survey,” writes Mr. Alfred Brooks, “is more refined than the rough triangulation done by our men; at the same time they were much further away.” “It is a curious coincidence,” he adds, “that the determination made by the Coast Survey was the mean which we had assumed from our three determinations” (twenty thousand three hundred feet).
Theodolites and Barometers
There are, however, two sources of error in the determination of the height of this mountain by triangulation—a general one and a particular one. The general one lies in the difficulty of ascertaining the proper correction to be applied for the refraction of the atmosphere, and the higher the mountain the greater the liability to this error; for not much is positively known about the angle of refraction of the upper regions of the air. The officers of the Trigonometrical Survey of Indiahave published their opinion that the heights of the great peaks of the Himalayas will have to be revised on this account. The report of the Coast Survey’s determination of the height of Denali claims a “co-efficient of refraction nearer the truth” than the figure used on a previous occasion; but a very slight difference in this factor will make a considerable difference in the result.
The particular source of error in the case of this mountain lies in the circumstance that its summit is flat, and there is no culminating point upon which the cross-hairs of the surveying instrument may intersect.
The barometric determination of heights is, of course, not without similar troubles of its own. The tables of altitudes corresponding to pressures do not agree, Airy’s table giving relatively greater altitudes for very low pressures than the Smithsonian. All such tables as originally calculated are based upon the hypothesis of a temperature and humidity which decrease regularly with the altitude, and this is not always the case; nor is the “static equilibrium of the atmosphere” which Laplace assumed always maintained; that is to say an equal difference of pressure does not always correspond to an equal difference of altitude. There is, in point of fact, no absolute way todetermine altitude save by running an actual line of levels; all other methods are approximations at best. But there had never been a barometric determination of the height of this mountain made, and it was resolved to attempt it on this expedition.
To this end careful arrangements were made and much labor and trouble undergone. The author carried his standard mercurial mountain barometer to Fort Gibbon on the Yukon in September, 1912, and compared it with the instrument belonging to the Signal Corps of the United States army at that post. A very close agreement was found in the two instruments; the reading of the one, by himself, and of the other, by the sergeant whose regular duty it was to read and record the instrument, being identical to two places of decimals at the same temperature.
Readings on the Summit
Arrangements were made with Captain Michel of the Signal Corps at Fort Gibbon, when the expedition started to the mountain in March, 1913, to read the barometer at that post three times a day and record the reading with the reading of the attached thermometer. Acknowledgment is here made of Captain Michel’s courtesy and kindness in this essential co-operation. The reading at Fort Gibbon which most nearlysynchronizes with the reading on top of the mountain is the one taken at noon on the 7th June. The reading on top of the mountain was made at about 1.50P. M., so that there was an hour and fifty minutes difference in time. The weather, however, was set fair, without a cloud in the sky, and had been for more than twelve hours before and remained so for thirty-six hours afterward. It would seem, therefore, that the difference in time is negligible. The reading at Fort Gibbon, a place of an altitude of three hundred and thirty-four feet above sea-level, at noon on the 7th June, was 29.590 inches with an attached thermometer reading 76.5° F. The reading on the summit of Denali, at 1.50P. M.on the same day, was 13.617. The writer is greatly chagrined that he cannot give with the same confidence the reading of the attached thermometer on top of the mountain, but desires to set forth the circumstances and give the readings in his note-book records.
The note-book gives the air temperature on the summit as 7° F., taken by a standard alcohol minimum thermometer, and it remained constant during the hour and a half we were there. The sun was shining, but a bitter north wind was blowing. But the reading of the thermometerattached to the barometer is recorded as 20° F. I am unable to account for this discrepancy of 13°. The mercurial barometer was swung on its tripod inside the instrument tent we had carried to the summit, a rough zero was established, and it was left for twenty minutes or so to adjust itself to conditions before an exact reading was taken. It was my custom throughout the ascent to read and record the thermometer immediately after the barometer was read, but it is almost certain that on this momentous occasion it was not done. Possibly the thermometer was read immediately the instrument was taken out of its leather case and its wooden case and set up, while it yet retained some of the animal heat of the back that had borne it, and the reading was written in the prepared place. Then when the barometer was finally read, no temperature of the attached thermometer was noted. This is the only possible explanation that occurs, and it is very unsatisfactory. It was not until we were down at the base camp again that I looked at the figures, and discovered their difference, and I could not then recall in detail the precise operations on the summit. It is hard to understand, ordinarily, how any man could have recorded the two readings on the same page of the book withoutnoticing their discrepancy, but perhaps the excitement and difficulty of the situation combined to produce what Sir Martin Conway calls “high altitude stupidity.”
In Exculpation
It is indeed impossible to convey to the reader who has never found himself circumstanced as we were an understanding of our perturbation of mind and body upon reaching the summit of the mountain: breathless with excitement—and with the altitude—hearts afire and feet nigh frozen. What should be done on top, what first, what next, had been carefully planned and even rehearsed, but we were none of us schooled in stoical self-repression to command our emotions completely. Here was the crown of nearly three months’ toil—and of all those long years of desire and expectation. It was hard to gather one’s wits and resolutely address them to prearranged tasks; hard to secure a sufficient detachment of mind for careful and accurate observations. The sudden outspreading of the great mass of Denali’s Wife immediately below us and in front of us was of itself a surprise that was dramatic and disconcerting; a splendid vision from which it was difficult to withdraw the eyes. We knew, of course, the companion peak was there, but had forgotten all about her, having had no slightest glimpse ofher on the whole ascent until at the one stroke she stood completely revealed. Not more dazzling to the eyes of the pasha in the picture was the form of the lovely woman when the slave throws off the draperies that veiled her from head to foot. Moreover, problems that had been discussed and disputed, questions about the conformation of the mountain and the possibilities of approach to it, were now soluble at a glance and clamored for solution. We held them back and fell at once to our scientific work, denying any gratification of sight until these tasks were performed, yet it is plain that I at least was not proof against the disturbing consciousness of the wonders that waited.
It was bitterly cold, yet my fingers, though numb, were usable when I reached the top; it was in exposing them to manipulate the hypsometrical instruments that they lost all feeling and came nigh freezing. And breathlessness was naturally at its worst; I remember that even the exertion of rising from the prone position it was necessary to assume to read the barometer brought on a fit of panting.
Calculations for Altitude
With these circumstances in mind we will resume the discussion of the readings taken on the summit and their bearing upon the altitude ofthe mountain. It seems right to disregard the temperature recorded for the attached thermometer, and to use the air temperature, of which there is no doubt, in correcting the barometric reading. So they stand:
Bar.Temp.13.617 inches7° F.
The boiling-point thermometer stood at 174.9° F. when the steam was pouring out of the vent.
They stand therefore:
Now, the tables accessible to the writer do not work out their calculations beyond eighteen thousand feet, and he confesses himself too long unused to mathematical labors of any kind for the task of extending them. He was, therefore, constrained to fall back upon the kindness of Mr. Alfred Brooks, the head of the Alaskan Division of the United States Geological Survey, and Mr. Brooks turned over the data to Mr. C. E. Giffin, topographic engineer of that service, to which gentleman thankful acknowledgment is made for the result that follows.
Fort Gibbon and Valdez as Bases
Ignoring a calculation based upon atemperature of 20° F. on the summit, and another based upon a temperature of 13.5° F. on the summit (the mean of the air temperature and that recorded for the attached thermometer) and confining attention to the calculation which takes the air temperature of 7° F. as the proper figure for the correction of the barometer, a result is reached which shows the summit of Denali as twenty-one thousand and eight feet above the sea. It should be added that Mr. Giffin obtained from the United States Weather Bureau the barometric and thermometric readings taken at Valdez on 7th June about the same length of time after our reading on the summit as the reading at Gibbon was before ours. From these readings Mr. Giffin makes the altitude of the mountain twenty thousand three hundred and seventy-four feet above Valdez, which is ten feet above the sea-level. From this result Mr. Giffin is disposed to question the accuracy of the reading at Gibbon, though the author has no reason to doubt it was properly and carefully made. Valdez is much farther from the summit than Fort Gibbon and is in a different climatic zone. The calculation from the Valdez base should, however, be taken into consideration in making this barometric determination, and the mean of the two results, twentythousand six hundred and ninety-six feet, or, roundly,twenty thousand seven hundred feet, is offered as the contribution of this expedition toward determining the true altitude of the mountain.
The figures of Mr. Giffin’s calculations touching the altitude of this mountain and also determining the altitudes of various salient points or stages of the ascent of the mountain are printed below:
