Union Peak

Union Peak is a 7,709-foot mountain featuring a distinctive rock spire at its summit, shaped by ancient volcanic activity. The peak rises prominently above the surrounding landscape within Crater Lake National Park with steep slopes and rocky terrain.

The peak was named in 1853 by the Nye expedition party during their exploration of the region, chosen to express allegiance to the Union. This naming reflects the national significance attached to that period of exploration.

The mountain serves as a training ground for mountaineers who practice technical climbing skills on its challenging rock formations throughout the year.

The route to the summit is steep and technical, requiring climbing experience and solid physical fitness before attempting it. Visitors should expect rough rocky terrain and be aware that conditions vary by season, affecting difficulty and access.

The rock formations expose volcanic plugs that survived glacial erosion, revealing geological layers spanning millions of years of volcanic history. These formations allow visitors to witness the ancient geological story written in stone on the mountainside.
