2022 Map of Devils Backbone
USGS Topo · Published 2022About this map
The Devils Backbone ridge dominates this section of the Texas Hill Country, carving a path between the Blanco River to the north and the expansive Canyon Lake reservoir to the south. This modern survey illustrates a landscape defined by dramatic elevation changes, where deep hollows like Heiser Hollow and Shelton Hollow cut through the limestone terrain. The border between Hays and Comal counties bisects the quadrangle, passing through a network of winding ranch roads and newer residential developments that radiate from FM 32.
