1925 Map of Pearsall 1-b

About this map

The Frio River carves a deep, winding path through this corner of Frio County, joined by a network of drainage systems including Hondo Creek and Buck Creek. This 1925 survey by T.F. Murphy and W.A. Fisher utilized early aerial photography from the U.S. Army Air Service to chart the complex topography of the river basin. The landscape is defined by its hydrology, where the Cood Crossing provides a rare transit point across the river's meandering channel. Other prominent water features include Elm Creek and Palo Blanco Creek, which contribute to the intricate drainage pattern of the region. The map also documents numerous benchmarks, such as BM P Tr 44 587, establishing precise vertical control across this rural Texas landscape during a period of transition in surveying technology.
