About this map

Whitney Ridge and the Virgin Mountains dominate the northern landscape of this borderland, where the high desert terrain of Clark County meets the Mohave County line. The topography is defined by seasonal drainages and dry watercourses, including the descriptively named Pussy Willow Wash, Black Wash, and Mud Wash. This arid environment, part of the northern Mojave Desert, relies on rare water points such as Mud Wells for sustenance in an otherwise parched basin.

Transportation through this portion of the Saint Thomas Gap relies on primitive routes and unpaved corridors. Significant local transit is facilitated by the New Gold Butte Rd and Grand Gulch Rd, which provide access to the Wechech Basin. These roads reflect the long-standing infrastructure patterns required to navigate the complex landform of the gap, where Horse Spring Wash carves a path through the southern reaches of the quadrangle.
