Nature
Mount Drum is a stratovolcano at the western end of Alaska’s Wrangell Mountains, notable for the dramatic rise of its flanks above the surrounding tundra, glacier headwaters, and the Copper River. Active roughly between 650,000 and 240,000 years ago, it later developed dacitic domes around its summit before a major explosive event destroyed the volcano’s southern half and left the steep south face above the Nadina Glacier. Nearby mud volcanoes mark the area’s only historic activity. Named in 1885 for Richard Coulter Drum, the mountain was first climbed in 1954, and a 1968 ascent established the standard route.
