1983 Map of Bullis Gap

About this map

Bullis Gap Range dominates this West Texas landscape along the international border in the early 1980s. The topography is defined by a complex network of drainage systems including Kellogg Canyon, Jackson Canyon, and Silber Canyon, all descending toward the Rio Grande Rio Bravo. Human presence is sparse, centered on the Bullis Gap Ranch and its associated Landing Strips, which indicate the necessity of aerial access in this remote portion of Brewster County. Across the river in Coahuila, Mexico, small settlements like C. El Recodo and C. El Mexicano sit near the water's edge below the heights of Lomas de las Palmas. The map illustrates a borderland economy reliant on water management, evidenced by numerous tanks and draws that sustain the arid terrain between Mount Karen and the river.
