2021 Map of State Line Pass

About this map

The Clark Mountain Range and Spring Mountains anchor this 2021 map, illustrating a high-desert landscape defined by the interstate boundary between California and Nevada. As the terrain shifts from the eastern floor of the Ivanpah Valley across the State Line Hills, the map traces the intersection of San Bernardino County and Clark County. This modern survey provides clear documentation of the topographic transitions at State Line Pass and Stateline Pass, offering a precise record of the mountain gaps and dry washes like Porter Wash that have historically guided movement across this arid divide. The presence of prominent summits such as Devil Peak and Little Devil Peak highlights the topographical isolation of the Mojave Desert interior, while the delineation of the Mesquite Valley to the west marks the extent of the high mountain influence over local basins.
