Geography

The drainage basin stretches approximately from the Little San Bernardino Mountains north of Interstate 10 in the south, to the Interstate 40 area in the north. Lying within the Mojave Desert, the Morongo Basin is east of the city of San Bernardino and San Bernardino Mountains, and north of the Coachella Valley and Colorado Desert.
The Morongo Basin is located within the Mojave Desert and in the High Desert region of Southern California. The area's elevation can range from 1950 ft in Twentynine Palms, to 3000 ft in Yucca Valley. The higher sections of Joshua Tree National Park are within the basin.
The terrain in the area is a desert landscape of hills and alluvial fans framed by mountain ranges.
Natural history
The Mojave yucca (Yucca schidigera) (namesake of Yucca Valley) and the Joshua tree (Yucca brevifolia) (namesake of Joshua Tree city and park) are notable native plants in the region.
The basin's habitats are home to Black-tailed jackrabbits, coyotes, and the Mojave Rattlesnake (Crotalus scutulatus).
