2022 Map of Roys Peak

About this map

Big Bend National Park dominates this high-desert landscape in Brewster County, defined by the drainage patterns of Tornillo Cr and the imposing heights of Roys Peak. The map highlights a transition from the drainage basins of Dugout Draw to the dramatic elevation of the McKinney Hills and the Sierra del Carmen range. Evidence of the region's rare water sources appears in labels like Willow Tank and Carlota Tinaja, vital landmarks in an arid environment. Transportation through this corner of the park is limited to the Rio Grande Village Road and primitive routes such as the Telephone Canyon Trl and Ernst Tinaja Trl. Significant geological formations like the Banta Shut-In and the sunken topography of Ernst Basin provide essential context for understanding the natural barriers and pathways of the Chihuahuan Desert.
