2016 Map of Gilliland Peak

About this map

Glass Mountains terrain dominates this Brewster County landscape, where the high desert environment is defined by dramatic limestone ridges and isolated volcanic summits. The topography centers on Gilliland Peak, with several other named elevations including Cathedral Mtn, Iron Mtn, and Chichi Peak providing distinct landmarks for navigation and land claims. Drainage patterns in this arid region are primarily seasonal, carved into features such as Gilliland Canyon, Road Canyon, and Moose Draw. The eastern portion of the survey tracks the course of Peña Colorado Cr, a vital water source in this part of West Texas. This 2016 representation of the area illustrates the enduring character of the high-country range, showing few signs of modern development across the intricate contour lines of the mountains.
