The Arco-Minidoka (A-M) Road begins southwest of Arco, just off US-20. From the junction of US-20 and US-93 in downtown Arco, drive west on US-20 for 1.9 miles. Turn left/south onto [signed] 3100W. This is the A-M Road. Drive 10.2 miles south then southeast on the A-M Road to a weak 2-track road on the right/west side of the road. Park here (5,347 feet).

The Climb

From the road junction, bushwhack west through gapped sagebrush to the summit, which is located at the right/north end of an elongated summit ridge. The official summit has a pole on top and triangulation posts nearby but a rocky outcrop just to its north has a torn-down cairn and appears to be slightly higher. I could not locate a USGS benchmark on the summit.
