2021 Map of In-Ko-Pah Gorge

USGS Topo · Published 2021

About this map

Ocotillo and the surrounding high desert terrain define this corner of the California-Mexico border region, where the Jacumba Mountains drop toward the Imperial Valley. This landscape is marked by the dramatic descent of In-Ko-Pah Gorge and the winding course of Devils Canyon. The historical importance of this corridor for travel is evident in the alignment of modern routes near the traditional Mountain Spring and Boulder Park areas, which served as vital stopovers for transcontinental travelers transitioning from the mountain passes to the desert floor. The map tracks seasonal drainage patterns through Palm Canyon Wash and Myer Creek, illustrating how water shaped the accessibility of Myer Valley and Davies Valley. These features reveal the geographic constraints that dictated early road building, from the steep grades of Mountain Springs Road to the remote expanses of Pinto Canyon.
