Mount McLoughlin is a dormant stratovolcano in southern Oregon’s Cascade Range, rising 9,493 feet in the Sky Lakes Wilderness and dominating the Rogue River Valley as the tallest volcano between Mount Shasta and Crater Lake. Geologically young, its cone formed largely within the last 200,000 years through three eruptive phases, with activity ending between 30,000 and 20,000 years ago. Glaciers later carved parts of the mountain, including a hollow amphitheater on its northeastern side. Long important to Native peoples, it figured in regional traditions and bore several Indigenous names before receiving its present name around 1838 in honor of John McLoughlin.
