2018 Map of Morongo Valley

About this map

Morongo Valley sits at a topographic crossroads where the San Bernardino Mountains meet the Little San Bernardino Mountains. This 2018 survey documents the residential expansion of communities like Little Morongo Heights and Palm Wells within a landscape defined by deep drainages and intermittent water sources. The map details the complex network of canyons that feed into the northern Coachella Valley, including the massive Big Morongo Canyon and the more secluded White House Canyon. Natural water features such as Leopard Spring, Sherman Shady Spring, and the Morongo Lakes underscore the critical role of water in this high-desert environment. The transition between the high desert and the lower valley floor is marked by the winding courses of Dry Morongo Creek and the Dry Morongo Wash, which traverse the county line between San Bernardino and Riverside.
