Arc Dome Wilderness

Arc Dome Wilderness is a protected region spanning approximately 115,000 acres across the Toiyabe Range, with mountain peaks, valleys, and distinct ecological zones at different elevations. The terrain rises across considerable elevation changes and displays shifting habitats ranging from dry sagebrush areas to forested slopes.

The area received protection from the United States Congress in 1989 and became part of the Humboldt-Toiyabe National Forest system. This designation reflects a growing recognition of the importance of undeveloped mountain landscapes for nature conservation and recreation.

The Toiyabe Crest Trail runs through this area and connects walkers to routes shaped by generations of outdoor enthusiasts. These paths remain central to how visitors experience and understand the mountain landscape today.

Visitors should bring sufficient water, navigation tools, and emergency supplies because this area lacks developed facilities or marked trails. Proper preparation is essential when traveling through this undeveloped terrain.

Birds such as the northern goshawk and sagebrush sparrow inhabit this protected area, making it important for watching these species in their natural setting. The Columbia spotted frog occupies water zones throughout the territory and adds to the region's animal diversity.
