About this map

Johnson Rancho anchors the northern boundary of this 1940s landscape, where the agricultural and industrial foundations of western Placer County are clearly visible. The Southern Pacific (Marysville Line) and Western Pacific railroads dictate the placement of settlements like Sheridan, Ewing, and the growing hub of Lincoln. This era shows a distributed rural infrastructure with small school districts serving local families, including Fairoaks Sch, Rivervale Sch, and Central Sch.

The terrain is defined by a series of southwestward-flowing drainages such as Coon Creek, Markham Ravine, and Pleasant Grove Creek. Industry is represented by the Clay Quarry located north of Lincoln, a site that historically underpinned the local economy. In the south, the early footprint of Roseville appears near Miners Ravine, illustrating the rail-centric development that would eventually transform the region.
