About this map

Long Valley serves as a stark corridor between the high peaks of the Plumas National Forest and the Fort Sage Mountains in this late 1970s survey. The landscape is defined by the critical infrastructure of the Western Pacific Railroad, which parallels Long Valley Creek and connects the small settlements of Constantia and Omira. This era shows a transition in land use, where traditional ranching and rail activity meet modern recreation at the Eagles Peak Ski Area on the western slopes.

Genealogists and local historians can trace isolated landmarks such as a lonely Grave near the railroad tracks or the remote Zamboni Hot Springs nestled at the base of the mountains. The map clearly delineates the convergence of three counties—Lassen, Plumas, and Washoe—along with the state line separating California and Nevada. From the high summits of Adams Peak to the canyon floor at Red Rock, the survey captures a rugged interior borderland during a period of relative quiet before further development.
