2015 Map of Twelvemile Knoll

About this map

California-Oregon Trl cuts across the northern reaches of this Wyoming landscape, marking a path of westward migration through the high desert. This 2015 survey by the U.S. Geological Survey illustrates the rugged drainage systems of Twelvemile Canyon and Simpson Gulch, which define the local topography south of the historic trail. The area is dominated by the prominent landmark Twelvemile Knoll, situated in the southwestern section of the quadrangle. Modern infrastructure, including Cr-49 and Blm-4204, follows the natural contours of the land, providing access through these public lands within the t25n r108w and t26n r108w townships. The map is a vital resource for understanding how ancient travel routes and modern Bureau of Land Management roads coexist in this arid terrain.
