how did the snake river get its name
Snake River More than 11,000 years ago, prehistoric Native Americans lived along the Snake. Salmon from the Pacific Ocean spawned by the millions in the river. These fish were central to the lives of the people along the Snake below Shoshone Falls. By the time Lewis and Clark crossed the Rockies and sighted the valley of a Snake tributary, the Nez Perce and Shoshone were the most powerful peoples in the region. Some tribes adopted use of horses after contact with Europeans, which reshaped their hunting and cultures for the next few hundred years before outside settlement. Later explorers and fur trappers further changed and used the resources of the Snake River basin. At one point, a hand sign made by the Shoshones representing fish was misinterpreted to represent a snake, giving the Snake River its name.
