On July 15, 1806, Captain William Clark and his party arrived at the Yellowstone River a short distance south of here after reaching the Rochejhone below its branch and below where it passes out of the Rocky Mountains. Clark recorded that the horses' feet were very sore and that many could scarcely proceed over the stone and gravel, though otherwise they were sound and in good spirits. The party stopped and rested for three hours to eat dinner and feed the horses. The next day Clark used a buffalo hide to make moccasins for the horses' sore feet, which seemed to relieve their misery. Over the next ten days, all their horses were taken by the Crow Indians who lived in the area.
