2018 Map of Hackberry Mountain

About this map

Hackberry Mtn dominates this high-desert landscape, serving as a prominent landmark within the southern reaches of the Mojave National Preserve. This 2018 survey documents a region defined by its vital water sources in an otherwise arid environment, specifically Hackberry Spring and Vontrigger Spring, which have historically supported local wildlife and travelers through the Mojave Desert. The topography transitions from the alluvial plains of Lanfair Valley into the elevated terrain of the Bobcat Hills and Vontrigger Hills. Drainage patterns are clearly defined by the course of Watson Wash, which cuts through the southern portion of the quadrangle. This map is an essential reference for understanding the modern conservation boundaries and natural hydrology of this portion of San Bernardino County, where the relationship between scarce springs and prominent peaks continues to shape the character of the eastern Mojave.
