About this map

Oak Island and Thelma anchor this portion of South Texas, where the landscape is defined by the winding course of the Medina River and its numerous tributaries. By 2010, the area shows a transition from rural reaches to more organized residential development, visible in the street grids near Royal Oaks Rd and the family-named corridors such as Devilbliss Ln and Trumbo Rd. The drainage network is complex, with Elm Creek, Palo Blanco Creek, and Gallinas Creek carving through the terrain before joining the larger river system.

A significant local landmark is Cannon Field, situated near the center of the survey. To the east, the impoundment at Pax Lake Dam creates Pax Lake, a prominent water feature in this otherwise semi-arid environment. The road network, including the heavily traveled Pleasanton Rd and W Jett Rd, illustrates the connectivity between these small communities and the broader Bexar County region, making it an essential reference for understanding the modern layout of these historic settlements.
