"We reached a point where the buttress was overhanging, and there was no other way of surmounting the difficulty than by passing around one side of it, which was the face of a vertical precipice of several hundred feet. Putting hands and feet in the crevices between the blocks I succeeded in getting over it, and when I reached the top found my companions in a small valley below. Descending to them, we continued climbing and in a short time reached the crest. I sprang upon the summit and another step would have precipitated me into an immense snow-field five hundred feet below. At the edge of this field was a sheer icy precipice, and then, with a gradual fall, the field sloped off for about a mile until it struck the foot of another lower ridge. I stood on a narrow crest about three feet in width. As soon as I had gratified the first feelings of curiosity I descended, and each man ascended in turn, for I would only allow one at a time to mount the unstable and precarious slab, which it seemed a breath would hurl into the abyss below. We mounted the barometer in the snow at the summit, and fixing a ramrod in the crevice, unfurled the national flag to wave in the breeze where never flag waved before." The elevation of this summit, as determined by Frémont, was 13,570 feet. His success on this expedition caused his most favorable reception by the War Department on his return to the States. [Illustration: Ascending Frémont's Peak.] Frémont's second expedition contemplated the connection of his first explorations with those made by Captain Wilkes on the Pacific Coast, so as to give a connected survey across the interior of North America. The party, which left Kansas City May 29, 1843, consisted of forty men, equipped with twelve carts for transportation and a light wagon for scientific instruments. The route followed was up the valley of the Kansas River, thence by the South Fork of the Platte to the vicinity of the present city of Denver. After considerable hesitation a northerly route was taken, skirting the westerly limits of the great Laramie plain, which brought Frémont to the emigrant trail in the vicinity of the South Pass. The volume of travel toward the Pacific Coast even at that early date may be estimated from his description of the Oregon trail as "a broad smooth highway where the numerous heavy wagons of the emigrants have entirely beaten and crushed the mountain sage."
