This peak can be accessed from the northeast via Succor Creek. See (A)(1) on page 346. The better access is from the south via the Northern Owyhee Crest Road. Use this link to read about this access: Reynolds Area Access Routes

Routes, Class 2

This peak will be Class 2 from either Succor Creek or the south. Use the link below to Brett Sergenian’s trip report to read about climbing the peak from Succor Creek. To climb the peak from the south drive as far as you dare on the Northern Owyhee Crest Road and then pick a route.

Brett Sergenian is the only person I know who has visited the peak from Succor Creek. His trip report is linked below. Also see the Reynolds Area Access Routes page. Brett climbed from Succor Creek. However, there are many lines that lead to the summit. Succor Creek can be difficult to cross during high water.
