La Mota Mtn and the surrounding Alazan Hills anchor this topographic study of Presidio County, where the high desert landscape is defined by drainage patterns and distinct plateaus. The north is dominated by the expansive Tascotal Mesa, which gives way to the deep cut of Old Ranch Canyon. Water management and movement are central to this area's geography, evidenced by the central path of Terneros Creek and the presence of Alazan Spring. Historical movement through this part of the Big Bend region is traced via remote routes like the Upper Leyva Trl and Encino Trl, which navigate the complex elevations between Lava Canyon and the higher ranching grounds. The map provides a detailed view of the infrastructure supporting this remote landscape, from Saucedo Rd to the various ephemeral drainages like Navajo Cr.
