Black Cap Peak is an isolated hump that separates Graveyard Canyon from the Dry Fork Creek Valley. The only black rock is on the summit cap. Prior to reaching that area, this is a scrub-bashing climb after leaving Graveyard Canyon Road. The summit offers a magnificent aerial view of the Dry Fork Creek Valley and the many cattle grazing in it. Due to private ranch land, Black Cap Peak can only be climbed from its east side.

Antelope Creek Road/FSR-137 is located 11.5 miles north of the Conoco gas station at the south end of Arco, ID on US-93. The junction is poorly signed so look for the road itself. Drive 13.6 miles southwest on FSR-137 to a road junction (or 2.7 miles southwest up Antelope Creek Road from the bridge crossing of Antelope Creek). Park at this [unsigned] road junction (6,130 feet). The jeep road heading left/southeast from here is Graveyard Canyon Road.

From the base of Graveyard Canyon Road, hike south up the primitive 2-track road (not advisable for driving) for about a mile to the “Spring” area indicated on the USGS topo map. This is an obvious marshy area just to the right/west of the road. Leave the road here and cross two pesky cattle fences, avoiding the worst of the mud and marsh. There will probably be cattle here to keep you company, at least for a little while.
From the “Spring” area, bushwhack due west to reach a ridge that blocks your view of Black Cap Peak. The peak is hidden behind this ridge on its own separate “island.” Cross the ridge and head southwest then west on a cattle trail that contours around the head of a drainage (to the north) to reach a saddle just below, and east, of Black Cap Peak. Scramble up easy scrub to the small, rocky summit. Yes, the talus and boulders of the summit cap ARE black. The summit has triangulation posts and remnants of three triangulation cairns but no summit cairn so I built one on the high point.
