Mount Wrangell
Modern Mount Wrangell, built upon the remnants of a mid-Pleistocene volcano, has an eruptive history spanning from 750,000 years ago to minor phreatic eruptions in 1884. The shield volcano features an ice-filled caldera 2.5 by 3.7 miles (4 by 6 km) in diameter at the top of Wrangell's broad summit. The caldera was apparently formed by subsidence rather than large explosive eruptions. The caldera is in turn rimmed by three small craters, which often display fumarolic activity with steam plumes that can sometimes be seen from a distance. The main summit is on the north side of the caldera, while the west summit rises to 14,013 feet (4,271 m). The summit region above 13,000 feet (4,000 m) in elevation is over 2 by 5 miles (3 by 8 km) in size. A very large cinder cone, 13,009-foot (3,965 m) Mount Zanetti, rises nearly 1,000 feet (300 m) above the northwest flank of Wrangell and is the source of some lava flows.

The same topography that leads to the heavy tidal currents also created the tsunami with the highest runup against a hillside in recorded history. On the night of July 9, 1958, an earthquake caused a landslide in the Gilbert Inlet at the head of the bay, generating a massive megatsunami which had sufficient…
