2014 Map of Arc Dome

About this map

Toiyabe National Forest encompasses this high-elevation landscape in the Toiyabe Range, dominated by the massive crest of Arc Dome and its Southeast Summit. The terrain is defined by deep drainages and canyons that carve through the mountains, including Belcher Canyon, Jett Canyon, and Niagara Canyon. Water patterns are distinct, with the Reese River flowing along the western slopes while the N Twin River and S Twin River extend eastward toward the Big Smoky Valley. High-altitude landmarks such as Toiyabe Dome and Mahogany Mtn anchor the southern and eastern reaches of the quadrangle. Historically, this area has served as a critical watershed and grazing ground, evidenced by features like South Twin Pasture, reflecting the long-standing land use within Nevada's Great Basin mountain ranges.
