Blanco River headwaters and a series of rugged limestone uplands define this portion of the Texas Hill Country near Whitworth Ranch. The landscape is etched by a complex drainage network where the S Fork Blanco River meets tributaries like Blackberry Cr and Delaware Cr. This 2016 survey illustrates the modern ranching and aviation footprint of the region, featuring private facilities like Headwaters Airport and Diamond K Ranch Airport set against prominent topographic landmarks such as Wolf Mtn, Meta Mtn, and the distinctive Bust Buttes. Local springs, including Wenzel Spring and Delaware Spring, suggest the underlying karst hydrology that has historically sustained these remote uplands. The road network, including Upper Sisterdale Rd and Habenicht-Fischer Rd, follows the winding contours of the creek valleys, connecting isolated ranching properties across Kendall County.
