1984 Map of Pilot Knob Valley West

About this map

U S Naval Reservation lands dominate this mid-1980s topographic study of the High Desert, where the rugged peaks of the Slate Range descend toward the floor of the Pilot Knob Valley. The landscape is defined by the sharp verticality of Straw Peak and the isolation of Willow Spring. Evidence of early 20th-century industry persists at the Ruins Mine Shafts, documenting the region's mining heritage in the southeastern corner of the quadrangle. Transportation is strictly limited by the military presence, as evidenced by the Randsburg Road (Restricted) traversing the valley floor. The map offers a precise view of the arid terrain and sparse improvements that characterized this part of San Bernardino County before modern desert management and technological shifts modified the remote basin.
