1972 Map of Chispa Mountain NW

About this map

The Wylie Mountains dominate this Trans-Pecos landscape as it appeared in the early 1970s, showcasing the stark topography of West Texas. This 1972 survey, field-checked by the Geological Survey and the Texas Water Development Board, reveals a desert environment where water sources are vital but sparse. Evidence of human activity is primarily limited to various instances of a Well or Tank scattered across the basin floors, indicating a reliance on groundwater for ranching or local survival. To the west, the Lobo Valley transitions into a significant Depression, while a pair of isolated Landing Strips provides a link to more distant settlements. The map illustrates a remote terrain where the physical geography dictating land use remains largely unchanged from the mid-century era.
