From the road junction, hike west up the sandy ATV trail to a ridge crest. Follow a weaker ATV trail (not shown on maps) left/south a short distance to reach the summit. There is no summit cairn. A few ground boulders (clustered together) are the high point. This peak is a combination of sand and sagebrush.
