The boundary between McMullen and Duval Counties bisects this South Texas ranch land, where the drainage network reveals the subtle topography of the Brush Country. Ephemeral waterways like Lagarto Cr and San Diego Cr thread through the landscape, eventually leading toward the Gulf Coast. In the northwest corner, the Devils Waterhole Hills rise as a localized elevation landmark above the surrounding flats. Human presence is defined by a thin network of rural roads and cattle tanks, such as Jug Tank. The isolated Campos Cem in the southwest provides a specific point of interest for genealogists tracing local families in this sparsely populated border region, while thoroughfares like FM 624 and Co RD 115 facilitate movement across the scrubland and private ranch holdings.
