About Idaho County

Idaho County, located in the north-central part of Idaho, has a rich and diverse history that spans thousands of years. The region was originally inhabited by Native American tribes, including the Nez Perce, Shoshone, and Blackfoot. These tribes relied on the abundant natural resources of the area, particularly the rivers and forests, for sustenance and trade.

European exploration of the area began in the early 19th century, with fur trappers and traders from companies like the Hudson's Bay Company venturing into the region. The Lewis and Clark Expedition also crossed through Idaho County in 1805, leaving behind written records of their encounters with the Native American tribes.

Idaho County was officially established in 1864, during the gold rush period in the Pacific Northwest. The discovery of gold in the Elk City area attracted miners from all over the world, leading to the rapid growth of settlements and the development of mining towns. Idaho County became one of the most important gold mining regions in Idaho, with towns like Warren and Florence experiencing boom and bust cycles as the mining industry fluctuated.

In addition to mining, the timber industry also played a significant role in the economic development of Idaho County. The abundant forests provided valuable resources for lumber and wood products, fueling the growth of sawmills and logging operations. Today, Idaho County has a diverse economy that includes agriculture, tourism, and outdoor recreation, all building upon the region's rich history and natural resources.
