2019 Map of Telephone Canyon

About this map

The Devils River winds through a complex network of dry drainage systems and dramatic relief in this modern topographic study of Val Verde County. This arid landscape is defined by its deep incisions, where the main river channel is fed by subterranean sources at Finegan Springs and seasonal runoff from numerous named canyons. To the north and west, the terrain is carved by Phillips Canyon, Huffstutler Canyon, and Bluff Canyon, while the namesake Telephone Canyon cuts toward the center of the sheet. The drainage patterns shift toward the east with landmarks like Button Willow Draw and Jack Cr, illustrating the watershed's significance in this part of Texas. These family-named canyons and draws, such as Miller Canyon and Sycamore Canyon, provide essential geographic markers for researchers tracing local land history and water rights in this limestone-carved region.
