The Middle Yuba River carves a deep path through the Sierra Nevada foothills on this map, marking the boundary between Sierra and Nevada counties. This landscape is defined by the legacy of hydraulic mining and gold-era infrastructure, evidenced by the extensive network of historical water conveyors like Plum Valley Ditch and Truckee Ditch. These ditches once fed the gravel mines that shaped the ridges and flats of this region.
