The Glass Mountains dominate this West Texas landscape, providing a striking transition from the high ridges down to the level expanse of the W B Flats. In the late 1960s, this area of Pecos County remained largely open ranch land defined by seasonal drainages and essential water infrastructure. The topography is anchored by the Marathon Gap, a natural pass through the limestone peaks that has long served as a primary transit corridor.
