1985 Map of Apache Gap

About this map

The Caballo Mountains dominate this arid landscape, where steep canyons and high peaks define the topography of Sierra County. Surveyed for this provisional edition in the early 1980s, the terrain is marked by essential water management features such as Apache Gap Tank, Slater Red Tanks, and L 7 Red Tank, reflecting the critical need for water storage in this high-desert environment. The map details a network of 4WD trails providing access to remote summits like Timber Mountain and Brushy Mountain. Local industrial history is noted through scattered Prospects and a Prospect near Lone Mountain, indicating the area's mineral exploration. Geologic and hydrological patterns are visible in the winding courses of Palomas Gap Creek and the deep cuts of Bat Cave Canyon and Apache Gap Canyon.
