But still there stretched ahead of us, and perhaps one hundred feet above us, another small ridge with a north and south pair of little haycock summits. This is the real top of Denali. From below, this ultimate ridge merges indistinguishably with the crest of the horseshoe ridge, but it is not a part of it but a culminating ridge beyond it. With keen excitement we pushed on. Walter, who had been in the lead all day, was the first to scramble up; a native Alaskan, he is the first human being to set foot upon the top of Alaska’s great mountain, and he had well earned the lifelong distinction. Karstens and Tatum were hard upon his heels, but the last man on the rope, in his enthusiasm and excitement somewhat overpassing his narrow wind margin, had almost to be hauled up the last few feet, and fell unconscious for a moment upon the floor of the little snow basin that occupies the top of the mountain. This, then, is the actual summit, a little crater-like snow basin, sixty or sixty-five feet long and twenty to twenty-five feet wide, with a haycock of snow at either end—the south one a little higher than the north. On the southwest this little basin is much corniced, and the whole thing looked as though every severe storm might somewhat change its shape.
So soon as wind was recovered we shook hands all round and a brief prayer of thanksgiving to Almighty God was said, that He had granted us our hearts’ desire and brought us safely to the top of His great mountain.
The Instrument Readings
This prime duty done, we fell at once to our scientific tasks. The instrument-tent was set up, the mercurial barometer, taken out of its leather case and then out of its wooden case, was swung upon its tripod and a rough zero established, and it was left awhile to adjust itself to conditions before a reading was attempted. It was a great gratification to get it to the top uninjured. The boiling-point apparatus was put together and its candle lighted under the ice which filled its little cistern. The three-inch, three-circle aneroid was read at once at thirteen and two-tenths inches, its mendacious altitude scale confidently pointing at twenty-three thousand three hundred feet. Half an hour later it had dropped to 13.175 inches and had shot us up another one hundred feet into the air. Soon the water was boiling in the little tubes of the boiling-point thermometer and the steam pouring out of the vent. The thread of mercury rose to 174.9° and stayed there. There is something definite and uncompromising about the boiling-point hypsometer; no tapping will make it rise or fall; it reaches its mark unmistakably and does not budge. The reading of the mercurial barometer is a slower and more delicate business. It takes a good light and a good sight to tell when the ivory zero-point is exactly touching the surface of the mercury in the cistern; it takes care and precision to get the vernier exactly level with the top of the column. It was read, some half-hour after it was set up, at 13.617 inches. The alcohol minimum thermometer stood at 7° F. all the while we were on top. Meanwhile, Tatum had been reading a round of angles with the prismatic compass. He could not handle it with sufficient exactness with his mitts on, and he froze his fingers doing it barehanded.
The View
The scientific work accomplished, then and not till then did we indulge ourselves in the wonderful prospect that stretched around us. It was a perfectly clear day, the sun shining brightly in the sky, and naught bounded our view save the natural limitations of vision. Immediately before us, in the direction in which we had climbed, lay—nothing: a void, a sheer gulf many thousands of feet deep, and one shrank back instinctively from the little parapet of the snow basin when one had glanced at the awful profundity. Across the gulf, about three thousand feet beneath us and fifteen or twenty miles away, sprang most splendidly into view the great mass of Denali’s Wife, or Mount Foraker, as some white men misname her, filling majestically all the middle distance. It was our first glimpse of her during the whole ascent. Denali’s Wife does not appear at all save from the actual summit of Denali, for she is completely hidden by his South Peak until the moment when his South Peak is surmounted. And never was nobler sight displayed to man than that great, isolated mountain spread out completely, with all its spurs and ridges, its cliffs and its glaciers, lofty and mighty and yet far beneath us. On that spot one understood why the view of Denali from Lake Minchúmina is the grand view, for the west face drops abruptly down with nothing but that vast void from the top to nigh the bottom of the mountain. Beyond stretched, blue and vague to the southwest, the wide valley of the Kuskokwim, with an end of all mountains. To the north we looked right over the North Peak to the foot-hills below, patched with lakes and lingering snow, glittering with streams. We had hoped to see the junction of the Yukon and Tanana Rivers, one hundred and fifty miles away to the northwest, as we had often and often seen the summit of Denali from that point in the winter, but the haze that almost always qualifies a fine summer day inhibited that stretch of vision. Perhaps the forest-fires we found raging on the Tanana River were already beginning to foul the northern sky.
Denali’s Wife from the summit of Denali
It was, however, to the south and the east that the most marvellous prospect opened before us. What infinite tangle of mountain ranges filled the whole scene, until gray sky, gray mountain, and gray sea merged in the ultimate distance! The near-by peaks and ridges stood out with dazzling distinction, the glaciation, the drainage, the relation of each part to the others all revealed. The snow-covered tops of the remoter peaks, dwindling and fading, rose to our view as though floating in thin air when their bases were hidden by the haze, and the beautiful crescent curve of the whole Alaskan range exhibited itself from Denali to the sea. To the right hand the glittering, tiny threads of streams draining the mountain range into the Chulitna and Sushitna Rivers, and so to Cook’s Inlet and the Pacific Ocean, spread themselves out; to the left the affluents of the Kantishna and the Nenana drained the range into the Yukon and Bering Sea.
