The party continued along the lake shore, the usual mode of travel being 3 men in the boat, 4 with the animals on land. Doane’s horse was abandoned on November 26. All of the men were violently ill from the deer meat, the Lieutenant diagnosing the sickness as “cholera morbus.” The party was forced to lay over most of 2 days, but reached the outlet of the lake on November 30, started down river, and camped 2 miles downstream from the Buffalo Fork on that date, the boat having made about 30 miles that day. December 1st. Moved on down the river. Sergeant and myself still very weak. Camped opposite Gros Ventre Butte, which is in the middle of the valley, and in front of Mount Hayden (earlier name for the Grand Teton) and its mighty canyon. (From this description this camp appears to have been opposite Blacktail Butte, in the vicinity of the present location of Moose.) During the day Warren and White followed a herd of Elk ’til dark, but did not get one. Light snow on the ground. Weather warm. At noon 65 degrees. Distance 12 m. The boat now carries all the property as the animals can carry no more. The river is a fine broad stream but the current is that of a mountain torrent and the channel divides so often that we counted over one hundred islands today. Occasionally therefore, we came to shoal water by getting in the wrong shute and had to lift her over. The bed of the stream is entirely of coarse gravel and boulders, mostly of granite, and the banks are low. Fishing good, but fresh fish is too thin a diet to subsist on alone. We have now no coffee, sugar, tea, bacon, and worst of all, no tobacco. Nothing but a few beans left. The game is scarce and shy. I cannot hunt and keep the observations at the same time. The boat can now go faster than the stock, but we cannot separate, with “Mad River Canyon” in front of us.
