About this map

Susanville sits at the foot of the Diamond Mountains, serving as a central hub where the Susan River flows toward the expansive Honey Lake basin. This mid-1980s portrait of Lassen and Plumas counties reveals a landscape defined by significant public and military land holdings, including the sprawling Sierra Army Depot and the Northern Calif Correction Center. The transition from the high desert valley floor to the timbered heights of the Lassen National Forest and Plumas National Forest is clear, with the peaks of Thompson Peak and Diamond Mtn overlooking the settled corridor along Highway 395.

Industrial and transit history is recorded through the routes of the Southern Pacific and Western Pacific railroads, which once serviced the mining and timber operations of the region. Local history researchers can find smaller settlements such as Johnstonville, Janesville, and Milford, along with specific resource sites like the Eagle Mine Upper Camp and Red Rock Mine. The map also highlights significant conservation areas including the Honey Lake State Wildlife Area and Dixie Mountain State Game Refuge.
