About this map

The Old Overland Stage Rte traces a historic passage through the arid landscape of southwestern Imperial County, following the base of the Fish Creek Mountains. This rugged terrain is defined by the steep elevation changes of Barrett Canyon and the expansive, flat stretches of West Mesa. The drainage patterns are dominated by the Carrizo Wash, which meanders across the southeastern quadrant of the survey area, indicating the seasonal water flow that has shaped this desert environment. Published by the U.S. Geological Survey, this 2018 edition provides a detailed look at the public land survey system grid across these townships, preserving the alignment of historical travel routes amidst the natural topography.
