Borah Peak

Borah Peak is the highest summit in Idaho at 3,859 meters and sits within the Lost River Range. The mountain offers multiple climbing routes with varying levels of difficulty for different experience levels.

The mountain was named in 1934 by the U.S. Geological Survey after William Borah, a prominent U.S. Senator from Idaho. The naming honored his significant role in the state's history.

Climbers from the region share a long tradition of attempting to reach the summit, with the southwestern approach being particularly well-known among mountain enthusiasts. The climbing community uses this place to test skills and connect with fellow mountaineers.

The route to the summit requires technical climbing skills and proper equipment because of the steep terrain. Visitors should prepare for physically demanding conditions and changing weather patterns.

A powerful earthquake in 1983 lifted the peak by about 30 centimeters while the nearby Lost River Valley dropped by about 2.4 meters. This geological event made the region an important site for earthquake research.
