2015 Map of Twelve Gauge Lake

About this map

Twelve Gauge Lake sits as a central landmark in this portion of the Mojave Desert within San Bernardino County. This arid landscape is defined by its surveyor-straight section lines and a sparse network of desert roads, including Santa Fe Ave and Harper Lake Rd. The terrain is generally open, though it rises to the prominent peak of Iron Mtn in the southeast corner. The grid layout, indicated by township and range markers such as t10n r4w, shows the systematic organization of the public land survey system. This 2015 edition provides a detailed perspective on the geography of the high desert prior to more recent developments, showing the exact relationship between the seasonal basin of the lake and the surrounding mountain and road infrastructure.
