About this map

Mojave National Preserve and the southern reaches of Castle Mountains National Monument define this portion of the High Desert. The landscape is characterized by the wide expanse of Lanfair Valley, where the small settlement of Lanfair sits at the junction of Ivanpah Rd and Cedar Canyon Rd. The topography is marked by distinct geological formations including the Grotto Hills and Lanfair Buttes, which rise abruptly from the Mojave Desert floor.

This 2021 survey illustrates the modern conservation boundaries that protect these arid ecosystems while showing the persistent road network that has served the region for decades. The grid-like division of public land surveys underscores the vast, open character of eastern San Bernardino County, maintaining a record of the primitive routes that cross the valley and the isolated peaks that serve as navigational landmarks.
