About this map

The border between Dimmit and Webb Counties bisects this South Texas landscape, where the seasonal drainage of Bonito Cr and its southern branch, Bonito S Br, carve through the terrain. The area is characterized by large-scale ranching operations and limited infrastructure, anchored in the north by the Briscoes Catarina Ranch Airport. A network of rural arteries including FM 2688 and Ranch Rd 5350A provide the primary access through this brush country, connecting disparate points across the county line. The presence of Espejo in the southern portion of the quadrangle highlights the local hydrography that defines land use in this arid region. The spatial arrangement of ranch roads and remote airstrips reflects the modern era of private land management and aerial logistics in this portion of the Rio Grande plain.
