San Juan Ridge dominates this northern Gold Country landscape, where the legacy of hydraulic mining is etched into the terrain near French Corral. This settlement, once a primary hub for the region's mining operations, is marked by a Historical Monument and sits just uphill from the Yuba River. To the west, the river is harnessed by the New Colgate Powerhouse, while downstream the South Yuba River meanders through the South Yuba River Project State Park Unit.
