The Devils Backbone ridge dominates this 1963 survey of the Texas Hill Country, following the serpentine boundary between Hays and Comal Counties. This period captures the landscape shortly after the construction of the Canyon Dam, showing the Canyon Reservoir at its normal pool elevation of 909 feet, with boat ramps already established for early recreational use. The terrain is deeply dissected by drainages such as Carpers Creek, Sorrel Creek, and Jacobs Creek, which flow toward the Guadalupe and Blanco rivers.
