1971 Map of Roys Peak

USGS Topo · Published 1974

About this map

Big Bend National Park dominates this 1971 study of the Chihuahuan Desert landscape, centered on the prominent Roys Peak and the surrounding Mc Kinney Hills. The drainage pattern is defined by Tornillo Creek and its many seasonal tributaries like Dugout Draw, which cut through the limestone and clay of the Texas backcountry. This specific quadrangle captures a network of historic transit routes, including the Old Ore Road and the Telephone Canyon (Pack) Trail, which navigate the steep eastern edge of the Sierra Del Carmen. In a landscape where water is scarce, the map identifies critical natural catchments such as Ernst Tinaja, Carlota Tinaja, and Willow Tank. Evidence of previous habitation or ranching activity appears near the southern reach of the creek at the site of Ruins, while the unique narrow passage at Banta Shut-in marks a significant geological bottleneck in the local watershed.
