Leadore

Near the head of the Lemhi Valley, mountain streams join to form the Lemhi River, which flows northwest towards the Salmon. The valley was home to the Lemhi Shoshone, or Agaidika, whose name refers to salmon. They caught fish in the river, including by means of weirs. In 1805 Lewis and Clark crossed the nearby Continental Divide and met Shoshone people in the valley. The Shoshone provided horses and a guide for the expedition's difficult journey across the mountains.
