About this map

Millican Mountains and the surrounding rangeland of Coke County are documented here through a combination of early 1960s photogrammetry and mid-1980s updates. The landscape is defined by its drainage systems and water infrastructure, essential for ranching in this arid Texas environment. Numerous named landmarks such as the Schooler Windmill, Halley Windmill, and Bull-Pasture Windmill point to the historic reliance on groundwater.

A significant feature of the 1987 revision is the inclusion of Lake E V Spence, showing its planned normal pool and 1986 water levels. The terrain is marked by deep canyons and draws, including Horse Canyon and Sterman Draw, which feed into major watercourses like Grape Creek and Wildcat Creek. This survey captures the region as it transitioned with the introduction of major reservoirs and cross-country pipelines.
