2024 Map of Black Ridge Crater

About this map

Black Ridge Crater dominates the lower-left portion of this landscape, its volcanic form defined by concentric contour lines that rise above the surrounding terrain. This portion of the Snake River Plains in Lincoln County is characterized by the distinct lack of surface water or established roads, highlighting the geology of this basaltic region. The map preserves the geometric precision of the Public Land Survey System, with boundaries such as t4s r21e and t5s r21e overlaying the lava-scoured topography. This survey captures the sparse, open character of the Idaho desert before any modern human development reached this specific quadrangle.
