1980 Map of Sevenmile Canyon

USGS Topo · Published 1980

About this map

Sevenmile Canyon and its complex network of tributaries define this high-desert landscape along the border of Terrell and Val Verde counties. The geography is dominated by deep drainage systems like Osman Draw and Outlaw Canyon, which cut through the arid terrain. Human presence is sparse, indicated primarily by isolated water infrastructure essential for ranching and survival in the Trans-Pecos region. Named points such as Hoddy, several Well sites, and a Tank highlight the critical role of water management in this semi-arid environment. In the southern reaches of the sheet, the terrain drops toward Mile and One-Half Canyon, illustrating the relentless erosive forces that have shaped this portion of the Edwards Plateau. The lack of major roads or settlements reflects a remote ranching economy focused on large-scale land holdings and sustainable water access.
