Arc Dome is within the traditional homeland of the Newe (Western Shoshone). Arc Dome was originally called Mount Poston and has also been known as Toiyabe Dome or Toyabe Dome. The name Toiyabe originates from the Newe word for mountain. Native people have been living on and with these lands for countless generations.
Friends of Nevada Wilderness commitment to stewardship of the Arc Dome Wilderness includes working with managing agencies and partner organizations to run an intensive trail maintenance crew, assure that area is regularly monitored, ecological impacts are rehabilitated, and vehicular incursions into wilderness are closed and the damage is restored.
