2021 Map of Twelve Gauge Lake

About this map

Twelve Gauge Lake sits at the heart of this arid landscape, a prominent hydrological feature within the sprawling Mojave Desert. The map reveals a highly structured grid of desert roads and survey lines, including Santa Fe Ave and Powerline Rd, which cut across the basin floor. This network reflects the systematic management of public lands and utility corridors in modern San Bernardino County. To the southeast, the terrain rises sharply toward the peak of Iron Mtn, where the topography becomes increasingly complex. Local transport routes like Helendale Rd and Harper Lake Rd provide access to this isolated region, while Iron Mountain Rd skirts the base of the namesake mountain. The sparse distribution of named features underscores the remote, open character of this high desert territory.
