Idaho random facts
Lemhi County, located in Idaho, has a rich history that dates back thousands of years. The region was originally inhabited by various indigenous tribes, including the Shoshone and Bannock peoples, who relied on the land's abundant natural resources for their sustenance. In the early 1800s, European explorers and fur trappers, such as Lewis and Clark, made their way through this region, establishing contact with the native tribes.

In the mid-19th century, Lemhi County experienced a significant influx of settlers due to the discovery of gold. The Lemhi Valley Gold Rush attracted many prospectors, leading to the establishment of mining camps and towns. Salmon City, later renamed Salmon, became the county seat and a hub of economic activity.

During this time, conflicts between settlers and indigenous peoples arose. The Bannock War of 1878, which spread throughout the region, resulted in the loss of lives and heightened tensions between the two groups. Eventually, a treaty was signed, granting the Lemhi Shoshone a reservation.

Throughout the 20th century, Lemhi County continued to develop and diversify its economy. Agriculture, mining, and timber industries played significant roles. The region also became an attractive destination for outdoor enthusiasts, thanks to its pristine rivers, mountains, and wildlife.

Today, Lemhi County preserves its historical legacy while embracing modern progress. It serves as a gateway to the Frank Church-River of No Return Wilderness and provides countless recreational opportunities. The county's rich history and natural beauty continue to attract visitors and showcase the enduring spirit of the region.
