Idaho was once home to one of the largest sawmills in the world. The Potlatch Lumber Company, which was based in the town of Potlatch, produced more than 2 billion board feet of lumber between 1906 and 1956.
Custer County is located in central Idaho and has a rich and varied history. It was originally home to Native American tribes such as the Shoshone and Bannock tribes, who relied on the abundant natural resources for their sustenance. The first European settlers arrived in the early 1800s, primarily fur trappers and explorers. However, it wasn't until the discovery of gold in the late 1800s that Custer County attracted a significant population.

The gold rush brought a wave of miners seeking their fortune, resulting in the establishment of several mining towns like Bonanza and Challis. The largest gold mine in the county, the Idaho-Maryland Mine, was one of the richest producers of gold in the state. However, like many mining towns, the boom didn't last, and by the early 1900s, most of the mines had closed, causing a decline in population.

In the early 20th century, Custer County experienced a shift from mining to agriculture. The fertile soil and favorable climate allowed for the growth of crops like potatoes, wheat, and hay. Ranching also became prevalent, with cattle and sheep grazing on the extensive grasslands. The town of Challis became the county seat in 1948, reflecting its growing importance in the region.

Today, Custer County is known for its stunning natural beauty, with vast mountain ranges, rivers, lakes, and forests. It attracts outdoor enthusiasts who enjoy activities like fishing, hunting, hiking, and camping. The county also preserves its history in various ways, with museums, historic buildings, and events that celebrate its past. Custer County continues to be a small, close-knit community, cherishing its heritage while embracing its role as a gateway to Idaho's backcountry.
