2019 Map of Lightning Hills

About this map

Blanca Springs serves as a vital water source in this arid Brewster County landscape, where the high desert terrain is defined by dramatic elevation changes. The map area is anchored by the Stillwell Mtn to the north and the namesake Lightning Hills in the southwest, separated by the winding course of San Francisco Cr. This drainage system, joined by Bragg Cr and Willow Cr, illustrates the complex topography of the Trans-Pecos region, where dry washes like Arden Draw only come alive during seasonal rains. A single artery, U.S. Highway 90, cuts across the northern half of the sheet, representing the primary connection through this sparsely populated ranching country. The proximity of the Warwick Hills further emphasizes the limestone-dominated geology that characterizes this portion of the Texas Big Bend hinterlands.
