1925 Map of Crowther No. 3

USGS Topo · Published 1925

About this map

The Frio River snakes through this South Texas landscape as it appeared in the mid-1920s, showing a complex drainage system across McMullen County. This specific survey was produced as an advance sheet by the State of Texas Board of Water Engineers, including members John A. Norris, C. S. Clark, and A. H. Dunlap. The map captures the meeting of several significant waterways, including the broad basin of San Miguel Creek and the smaller tributaries of Opossum Creek and Frenchman Br. A notable technical detail for this era is the use of aerial photographs from the U.S. Army Air Service to refine the culture and drainage data, a method that provides high precision for the braided channels of Elm Creek and the surrounding brush country topography.
