Thunder Mountain

Thunder Mountain is a summit in the Sierra Nevada reaching about 4,100 meters and positioned on the boundary between Sequoia and Kings Canyon national parks. The terrain consists of steep rocky ridges and a final climbing section to reach the peak.

The mountain received its first recorded climb in 1905 when a topographer from the United States Geological Survey reached the summit to place a benchmark. This early ascent was part of the systematic mapping effort of the Sierra Nevada region.

The peak draws mountaineers seeking challenging climbs that test their skills on steep rocky terrain. Its location between two major national parks makes it a notable destination within the regional climbing community.

The approach requires rock climbing experience and careful attention to route finding as paths can vary among multiple options. Starting early in the day and monitoring weather changes is important since conditions can shift rapidly at this elevation.

Thunder Pass on the mountain's eastern side marks the western terminus of the Kings-Kern Divide, an important geographical landmark. This pass serves as an orientation point for travelers moving between the two national parks.
