About this map

Great Basin National Park and Humboldt National Forest converge in this high-elevation terrain during the late 1980s. The landscape is defined by its dramatic limestone and quartzite features, most notably the massive Lexington Arch situated within Lexington Canyon. This natural formation is a rare example of a high-elevation arch, likely carved from ancient limestone.

Evidence of historical prospecting is scattered throughout the drainages, including the Bonanza Mine and an isolated Mine Shaft located near the South Fork Big Wash. Water sources like Cedar Cabin Spring and Chokecherry Spring provide vital points of interest for those tracking old trails or early twentieth-century land use. The map also delineates the Indefinite Boundary and various forks of Lexington Creek, illustrating the complex watershed of this eastern Nevada wilderness.
