The westernmost volcano of the Wrangell volcanic field, Mount Drum was formed during two cycles of activity between about 750 and 250 ka, the last of which included the emplacement of an arcuate ring of ten dacitic lava domes between 350 and 250 ka (Richter et al. 1994). The latest activity resulted in destruction of the southern half of the volcano and the formation of debris avalanches that covered a 200 km2 area during the late Pleistocene.
