2019 Map of Mariscal Mountain

About this map

Big Bend National Park dominates this desert landscape, where the dramatic elevation of Mariscal Mtn and its Mariscal Rim define the southern reaches of the region. A network of unpaved desert routes, including the Talley Road and Black Gap Rd, connects the remote terrain to the historic Glenn Springs to Hot Springs track. These paths follow the natural contours of the land, moving around the foothills of the Chisos Mountains and crossing ephemeral drainages like Fresno Cr. The availability of water in this arid environment is highlighted by Solis Spring, a critical landmark for travelers navigating the canyons and plateaus. This topographic survey records the modern state of the park's interior, showing how late-20th-century roads utilize traditional corridors through features like Cross Canyon.
