Mount Breitenbach

Mount Breitenbach stands in the Lost River Range of Idaho, reaching approximately 12,140 feet and ranking among the region's highest peaks. The mountain features multiple climbing approaches with steep sections and alpine terrain.

The summit was named in 1963 to honor Jake Breitenbach, a climber who died during the American expedition to Mount Everest that year. His legacy remains tied to this remote Idaho peak.

This peak draws mountaineers who come to test themselves on established climbing routes through the remote wilderness. The mountain has become a destination for climbers seeking a significant challenge in the Idaho backcountry.

The climbing season runs from mid-June through mid-September when snow melts and routes become most passable. Earlier in the season, heavy snow coverage makes the approach significantly more difficult.

The southwestern slopes rise nearly 1,890 meters (6,200 feet) above the Big Lost River Valley in a single massive wall. The northern face drops sharply toward the East Fork Pasimeroi River, creating a distinctive triangular profile when viewed from different angles.
