The Frio River meanders through the southern reaches of this South Texas landscape, joined by a drainage network of creeks that define the local topography. This 1930 edition, based on 1925 surveys, is notable for its use of early aerial photography from the U.S. Army Air Corps to compile cultural and drainage data. The small settlement of Crowther stands at a central junction of local tracks, positioned just north of the prominent Opossum Hill. The map is characterized by a significant area marked as a Preliminary Edition Unsurveyed Area to the north and east, leaving only the southwestern portion of the quadrangle with detailed contour data. This partial detail emphasizes the winding paths of San Miguel Creek and Elm Creek as they flow toward the Frio, providing a unique look at the rural landscape before more comprehensive modern surveys were completed.
