About this map

The Fort Irwin Military Reservation dominates this 1980s landscape, illustrating the intersection of military land use and the harsh terrain of the Mojave Desert. The northern extent of the sheet is defined by the high elevations of the Avawatz Mountains, where numerous mining markers such as Prospects and individual prospect pits dot the slopes. These features suggest a history of mineral exploration in the rugged peaks above the desert floor.

Evidence of human activity is sparse but specific, including a Radio Facility and isolated locations such as Grave and Grave Summit. Unusual features like a Spoil Bank and a Levee near No Name Lake indicate localized alterations to the natural drainage and landform. This survey provides a specialized view of the high desert before modern expansion, capturing the isolation of the San Bernardino County interior.
