1983 Map of Gilliland Peak

About this map

Gilliland Peak and Chichi Peak dominate the high ridges of the eastern Glass Mountains in Brewster County. This 1980s landscape reveals the infrastructure of Trans-Pecos ranching, where survival depends on a network of isolated water sources like West Pasture Well, Canyon Windmill, and Double Windmills. A single ranching complex, Iron Mountain Ranch, sits near the base of Iron Mountain in the eastern portion of the quadrangle. For those researching local history or genealogy, the map identifies specific small landmarks such as a lone Grave south of the peaks and a small Cem near the northern boundary. The terrain transitions from the heights of Cathedral Mountain into the drainage of Moose Draw, providing a detailed look at the land use and topography of West Texas during this era.
