2021 Map of Grommet

About this map

The Colorado River Aqueduct cuts a distinctive diagonal path across this desert landscape, a critical piece of water infrastructure accompanied by the service track of Aqueduct Rd. This remote corner of the Mojave Desert is defined by the stark transition between broad alluvial plains and steep desert ranges. The boundary between San Bernardino Co and Riverside Co bisects the map, separating the northern Vidal Valley from the southern reaches of Rice Valley. The topography is dominated by the West Riverside Mountains, where intricate contour lines reveal the complex drainage systems of Vidal Wash as it descends toward the valley floor. This map captures the intersection of mid-century engineering and the enduring geological features of the California desert.
