About this map

The Round Valley Indian Reservation dominates this mid-century survey, centering on the valley floor where the community of Covelo is situated. The landscape is defined by the winding course of the Eel River, which cuts through the mountainous terrain alongside the tracks of the Northwestern Pacific Railroad. Small settlements and stops like Spyrock, Nashmead, and Woodman are spaced along this vital rail corridor, reflecting the river-and-rail economy of northern Mendocino County during the early 1950s.

Higher elevations are marked by distinctive landmarks such as Updegraff Ridge and Island Mountain, while local infrastructure is captured through features like the Lake Mtn Sch and a cemetery near Covelo. Numerous tributaries including Blue Rock Creek and Grist Creek drain the surrounding hills into the Eel, illustrating the complex watershed that shaped early ranching and settlement patterns in the Round Valley region.
