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.
