Carson now organized a party of seven, and proceeded to a trading post called Brown's Hole, where he joined a company of traders to go to the Navajoe Indians. He found this tribe more assimilated to the white man than any Indians he had yet seen, having many fine horses and large flocks of sheep and cattle. They also possessed the art of weaving, and their blankets were in great demand through Mexico, bringing high prices, on account of their great beauty, being woven in flowers with much taste. They were evidently a remnant of the Aztec race. They traded here for a large drove of fine mules, which, taken to the fort on the South Platte, realized good prices, when Carson went again to Brown's Hole, a narrow but pretty valley about sixteen miles long, upon the Colorado River. After many offers for his services from other parties, Carson at length engaged himself for the winter, to hunt for the men at this fort, and as the game was abundant in this beautiful valley, and in the cañon country further down the Colorado, in its deer, elk, and antelope, reminding him of his hunts upon the Sacramento, the task was a delightful one to him. In the spring, Carson trapped with Bridger and Owen's with passable success, and went to the rendezvous upon Wind River, at the head of the Yellowstone, and from thence, with a large part of the trappers at the rendezvous, to the Yellowstone, where they camped in the vicinity for the winter, without seeing their old enemy, the Blackfeet Indians, until mid-winter, when they discovered that they were near their principal stronghold. A party of forty was selected to give them battle, with Carson, of course, for their captain. They found the Indians already in the field, to the number of several hundred, who made a brave resistance, until night and darkness admonished both parties to retire. In the morning when Carson and his men went to the spot whither the Indians had retired, they were not to be found. They had given them a "wide berth," taking their all away with them, even their dead. Carson and his command returned to camp, where a council of war decided that as the Indians would report, at the principal encampment, the terrible loss they had sustained, and others would be sent to renew the fight, it was wise to prepare to act on the defensive, and use every precaution immediately; and accordingly a sentinel was stationed on a lofty hill near by, who soon reported that the Indians were upon the move.
