They occasionally changed their camp and trapped along the banks of the Green, the Bear and the Salmon rivers.
During the winter one sad incident occurred.

Four of the trappers who were out in pursuit of game, were surrounded and overpowered by a numerous party of Blackfeet Indians, and all were killed.

There were buffaloes in abundance in that region, and these animals found ample forage, as they had the range of hundreds of miles, and instinct guided them to sheltered and verdant glens.

But in some of the narrow, wind-swept valleys the animals of the trappers suffered from exposure and want of food.

They were kept alive by cutting down cottonwood trees and gathering the bark and branches for fodder.
