About this area:
Divided east to west by the crest of the Sierra Nevada, Sierra County is comprised of two very different regions. The west side, where Highway 49 follows the North Yuba River up into the Lakes Basin area, is mountainous and heavily forested, supporting mining and logging industries. To the east is the Sierra Valley, which contains the communities of Calpine, Sattley, Sierraville, and Loyalton—the county’s only incorporated city. At 5,000 feet in altitude, the Sierra Valley’s wide-open ranchland is home to most of the county’s residents. Sierra is bordered by Plumas and Lassen counties to the north, Nevada County to the south, Yuba County to the west, and the state of Nevada to the east.
