They descended into the canyon with some difficulty, made some river measurements, and continued downstream. They camped about a mile below what Frémont called "Fishing Falls": "a series of cataracts with very inclined planes, which are probably so named because they form a barrier to the ascent of the salmon; and the great fisheries from which the inhabitants of this barren region almost entirely derive a subsistence commence at this place." He observed that the salmon were "so abundant that they Shoshone merely throw in their spears at random, certain of bringing out fish." This stretch of the river is now known as Salmon Falls. Early encounters between Europeans and Native Americans were generally friendly, but eventually brutal conflicts broke out over land ownership. After the Snake War, some twenty years later, the Shoshone were confined on reservations elsewhere.
