“We reached the camping place. What first struck our eye was several long rows of
Indian tents (lodges), extending along the Green River for at least a mile. Indians and
whites were mingled here in varied groups. Of the Indians there had come chiefly
Snakes, Flatheads and Nezperces, peaceful tribes, living beyond the Rocky
Mountains. Of whites the agents of the different trading companies and a quantity of
trappers had found their way here, visiting this fair of the wilderness to buy and to
sell, to renew old contracts and to make new ones, to make arrangements for future
meetings, to meet old friends, to tell of adventures they had been through, and to
spend for once a jolly day.”
—Adolph Wislizenus, a German traveler in the West
