The Climb
From the roadside pullout, bushwhack east up through thick-ish, but gapped, sagebrush to reach the brushy summit. The high point area is pretty small but walk around a bit to be sure that you stood on the high point. There is a small collection of rocks that appear to be a torn-down summit cairn amidst the sagebrush.
