The Little San Bernardino Mountains dominate the northeastern reaches of this survey, where the protected lands of Joshua Tree National Park provide a stark contrast to the developing residential patterns of the Coachella Valley below. This desert landscape is defined by the critical infrastructure that sustains it, most notably the path of the Colorado River Aqueduct as it cuts across the northern terrain and the Coachella Canal in the south. These engineering feats transformed the region, allowing for the growth of Indio.
