After a nearly disastrous attempt to cross “Lewis Fork” by bullboat and raft, the party discovered a ford, and then ascended Gros Ventre Fork. The party became lost in the mountains for several weeks, missing out on the Green River rendezvous. After extricating themselves from the craggy wilderness of the Absarokas, the party reached the Lamar River or East Fork of the Yellowstone, where they encountered some woebegone Sheepeater Indians, and lost a hunter. They apparently forded the Yellowstone at the lower end of the Grand Canyon near the mouth of Antelope Creek, at a point just above the spectacular Tower Falls and the Basaltic Cliffs where the river “rushes down a chasm with a dreadful roar echoing among the mountains.” From “Gardner’s Hole” the party then crossed the mountains to Gallatin and Madison forks, where they fell in with a trapping brigade under Bridger. Just below the Madison Canyon the combined forces were attacked by eighty Blackfeet and narrowly escaped massacre. The supply caravan under Fitzpatrick arrived at the Green River rendezvous on August 12, 1835. Accompanying him were two famous missionaries—Marcus Whitman, who distinguished himself among the trappers by extracting an Indian arrow from the back of Captain Bridger, and Reverend Samuel Parker, who alienated them by his overzealous moralizing. However, Parker made quite a hit with the assembled Flatheads and was so enthusiastic over their eagerness for Christian knowledge that it was decided that he would accompany them to their homes, while Whitman would return to the states to recruit help for a permanent mission in Oregon. Parker tells of his journey westward: August 21st, commenced our journey in company with Capt. Bridger, who goes with about fifty men, six or eight days’ journey on our route. Instead of going down on the southwest side of Lewis’ river, we concluded to take our course northerly for the Trois Tetons, which are three very high mountains, covered with perpetual snow, separated from the main chain of the Rocky Mountains, and are seen at a very great distance; and from thence to Salmon river.... On the 22d ... we ... arrived at what is called Jackson’s Hole [Jackson’s Little Hole].... Sabbath, 23d. Had an opportunity for rest and devotional exercises. In the afternoon we had public worship with those of the company who understood English. The men conducted with great propriety, and listened with attention.... Arose very early on the 24th, and commenced our way through the narrow defile, frequently crossing and recrossing a large stream of water [Hoback] which flows into the Snake river....
