Lemhi Shoshoni Tribe

In eastern Idaho, along Interstate 1-15 and 1-86, lies the 544,000-acre Fort Hall Indian Reservation on a small part of the land that the Shoshone and Bannock Indians have lived on for several thousand years.

Before recorded history, the Shoshone and Bannock originally roamed the areas of what are now the states of Wyoming, Utah, Nevada, and Idaho. In their search for food, they hunted, gathered, and fished for salmon. Horses introduced in the early 1700s allowed some groups to travel great distances in pursuit of buffalo.

The first white men to explore the west were the trappers and explorers. Sacajawea, a Lemhi Shoshone woman, accompanied Lewis and Clark through the west to the Pacific Ocean in 1805.

A Presidential Executive Order established the 1.8 million acre Reservation in 1867 but a survey error reduced the size of the Reservation to 1.2 million acres in 1872, and later encroachments reduced the Reservation to its present size.
