Timbered Dome is the southeastern-most named Pioneer Mountains summit. It is located WNW of Arco, Idaho. It is in fact, dome-shaped and timbered. It can be approached via rough 4WD roads from both the east and the west. A good map will help you get there. Be aware that there is a lot of private land that surrounds Timbered Dome and access is currently somewhat restricted. Check with the Challis BLM office before venturing into this area.
