2016 Map of Cupola Mountain

About this map

Cupola Mtn and Black Mtn define the high desert topography of this Brewster County region, where the land is carved by deep, winding drainages. The drainage patterns of Big Canyon and Reagan Canyon dominate the central and southern portions of the terrain, illustrating the dramatic elevation shifts characteristic of the Big Bend country. This 2016 survey by the U.S. Geological Survey captures a landscape largely defined by its natural geomorphology rather than human infrastructure, showing the isolation of these peaks and the complex network of ephemeral waterways that have shaped the limestone and volcanic features over millennia. For those studying the remote borderlands of West Texas, this map provides a precise record of the vertical relief and the intricate drainage systems that define this part of the Trans-Pecos.
