The Middle Fork Feather River carves a deep path through this portion of the Plumas National Forest, serving as the primary corridor for the Western Pacific Railroad and regional transport during the late 1930s. Industrial activity is concentrated at the northern and southern extremes of the sheet, anchored by the Walker Cons Mine near Walkermine and the Plumas Eureka Mine above Johnsville. These mining hubs, along with the Walker Mine Compressor, reveal the intense geological extraction that defined the local economy before the mid-century.
