Wetterhorn Peak, Mountain summit in San Juan Mountains, United States.

Wetterhorn Peak is a pointed rock spire in the northern San Juan Mountains, rising to 14,015 feet (4,272 m) in the Uncompahgre Wilderness. Its steep, triangular form contrasts with the broad bulk of nearby Uncompahgre Peak. The standard route climbs the southeast ridge from the Matterhorn Creek drainage, gaining 3,535 feet (1,077 m) with exposed Class 3/4 scrambling.

Wetterhorn Peak and neighboring Matterhorn Peak were named after the Wetterhorn and Matterhorn of the Swiss Alps, whose pointed forms they resemble. The first recorded ascent was made in 1906 by George Barnard, C. Smedley, W. P. Smedley and D. Utter, though miners working in the area in the 19th century may have climbed it earlier.

The peak's name comes from the Swiss Wetterhorn, which it resembles as a pointed rock spire; the neighbouring Matterhorn Peak is named the same way. The two spires stand out against the broad bulk of the higher Uncompahgre Peak, whose name comes from the Ute band that lived in the area.

Climbing this peak requires solid rock climbing skills, appropriate gear, and careful weather monitoring, as conditions can change rapidly. Summer months offer the most stable climbing window, though afternoon thunderstorms are common in the mountains.

The peak's name comes from the Swiss Wetterhorn, which it resembles as a pointed rock spire; its neighbour Matterhorn Peak is named after the Matterhorn. Both contrast with the broad bulk of Uncompahgre Peak, 2.75 miles (4.4 km) to the east, whose name comes from the Uncompahgre Ute people.
