About this map

Ringtail Mtn and Sinks Hill dominate the northern terrain of this Uvalde County region, where the Edwards Plateau begins to break toward the southern plains. The drainage network is particularly defined, featuring the winding Sabinal River on the eastern edge and the converging paths of Blanco Cr and Little Blanco Cr. The landscape is etched by named canyons and depressions like Turkey Hollow and Catclaw Hollow, indicating a karst topography common to the Texas Hill Country. Reiner Springs provides a rare point of permanent water in a landscape of seasonal creeks and intermittent flows. Tracing the path of Ranch Rd 1049 and Farm Rd 30 reveals how modern transportation follows the natural contours of the land, navigating around the prominent Horseshoe Bend and through the various hollows that define the local geography.
