This aerial view looks northeast across the trachytic shield volcano Mount Takahe, with an ice-filled 8-km-diameter caldera at the summit. The approximately 30-km-wide edifice rises about 2,000 m above the surrounding ice sheet. Eruption deposits indicate both subaqueous and subaerial eruptions, and include lavas and tephra. Möll Spur (right of center) is a prominent steep ridge of lava produced in two sequences at about 34 and 17 ka. The most recent eruption occurred around 5.6 ± 0.8 ka, producing widespread tephra distribution across West Antarctica.
