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....

... on the 25th, [we] encamped in a large pleasant valley, commonly called Jackson’s large hole. It is fertile and well watered with a branch of Lewis’ river coming from the southeast [Hoback], and another of some magnitude coming from the northeast [Snake River itself], which is the outlet of Jackson’s lake, a body of water situated just south of the Trois Tetons....

We continued in this encampment three days, to give our animals an opportunity to recruit, and for Captain Bridger to fit and send out several of his men into the mountains to hunt and trap....

On the 28th, we pursued our journey and passed over a mountain [Teton Pass] so high, that banks of snow were but a short distance from our trail. When we had ascended two-thirds of the way, a number of buffalo, which were pursued by our Indians, came rushing down the side of the mountain through the midst of our company....

In [Pierre’s Hole] ... I parted with Captain Bridger and his party, who went northeast into the mountains to their hunting ground, which the Blackfeet claim, and for which they will contend.

According to the impious Joseph L. Meek, the sermon on Sunday the 23rd in Jackson’s Little Hole (the site of which has been memorialized by the State of Wyoming as that of “the first Protestant sermon in the Rocky Mountains”) was not such a great success as Parker makes out, for, “in the midst of the discourse, a band of buffalo appeared in the valley, when the congregation broke up, without staying for a benediction,” and every man excitedly joined in the hunt.

Another who accompanied this expedition was Kit Carson. Parker gave Carson his initial shove into immortality by relating the story of his victory at the rendezvous over a “great bully” named Shunar:

Trappers at Old Faithful.

... I will relate an occurrence which took place near evening, as a specimen of mountain life. A hunter, who goes technically by the name of the great bully of the mountains, mounted his horse with a loaded rifle, and challenged any Frenchman, American, Spaniard, or Dutchman, to fight him in single combat. Kit Carson, an American, told him if he wished to die, he would accept the challenge. Shunar defied him. C. mounted his horse, and with a loaded pistol, rushed into close contact, and both almost at the same instant fired. C’s ball entered S’s hand, came out at the wrist, and passed through the arm above the elbow. Shunar’s ball passed over the head of Carson; and while he went for another pistol, Shunar begged that his life might be spared. Such scenes, sometimes from passion, and sometimes for amusement, make the pastime of their wild and wandering life.
