Gold-rush era settlements and deep river canyons dominate this landscape surveyed in 1932. The terrain is defined by the steep drainage basins of the North Fork American River, Middle Fork American River, and multiple branches of the Yuba River. Along the ridges, historic mining towns like Alleghany, North Bloomfield, and Dutch Flat are connected by early automotive routes including the Lincoln Highway and Victory Highway. The Southern Pacific RR carves a dramatic path through the mountains, notably passing through Colfax and around the steep grade at Cape Horn.
