1983 Map of Horn Spring

About this map

Turtle Mountains topography dominates this 1983 survey of the California desert, where the arid landscape is defined by extensive drainage networks such as the Vidal Valley. The map highlights the isolation of mineral exploration in this corner of San Bernardino County, centered on the Virginia May Mine. Resource extraction and water scarcity are central themes, evidenced by the presence of Horn Spring (Dry) and prominent landmarks like Horn Peak and Terrapin. The detailed contour mapping reveals the complex landforms of Black Ridge, while numerous survey markers and bench marks trace the pathways of earlier geological field checks. This provisional edition preserves the industrial and natural character of the high desert before modern developments altered the access to these remote peaks and dry washes.
