1983 Map of Cupola Mountain

About this map

Black Gap Wildlife Management Area anchors the southern portion of this West Texas terrain, where the landscape is defined by deep drainages and limestone summits. The map tracks the winding course of Reagan Canyon and Big Reagan Canyon as they carve through the high desert toward the Rio Grande corridor. Human presence is sparse, marked primarily by the isolated Stovall Ranch and a network of Jeep Trails and Trails that negotiate the steep contours between Black Mountain and Cupola Mountain. This 1983 edition, based on 1970s field data, captures the area's transition into a managed wildlife sanctuary, showing several remote water sources such as the Tank located along the northern canyons. The presence of an Indefinite Boundary reflects the complex surveying history of these remote Brewster County reaches.
