Mount Adams fumaroles reach 150 degrees at 12,269 feet elevation, emerging 136 degrees above ambient on Washington's second-highest volcano. Located just 7.9 meters from the South Climb route, these geothermal features occupy the upper flanks where volcanic heat meets glacial ice in the Gifford Pinchot National Forest.
The fumaroles lie in the alpine zone above all vegetation, surrounded by permanent snowfields and glaciers. Average annual air temperature is 14 degrees with 300.2 inches of snow and 65.9 inches total precipitation. Bare volcanic rock, ice, and steam vents characterize this extreme environment. Views extend across the Cascade Range to neighboring volcanoes.
History of Mount Adams Fumaroles
Mount Adams stands as a sacred peak to the Yakama Nation and other Indigenous peoples. Geothermal activity reflects the volcano's dormant but not extinct status, with the last eruption occurring roughly 1,000 years ago. The South Climb route has served mountaineers since systematic climbing began in the early 20th century.
Reaching the fumaroles requires technical mountaineering skills, proper glacier travel equipment, and conditioning for high altitude. Most climbers attempt the summit June through September. Takhlakh Lake Campground, 12 kilometers away at 4,400 feet, provides base camping. Register with the forest service and prepare for rapidly changing mountain weather.
