Exploring Antarctica's Active Volcano Mt. Erebus

Mount Erebus is one of Antarctica’s two active volcanoes and the southernmost active volcano on Earth. Conveniently, Erebus’ summit is a mere 25 miles from McMurdo Station. After a helicopter trip to its flank, at altitude in -30° F conditions Caitlin & Arlo embark on foot and see firsthand how breathtaking (literally) Erebus is — and why an active volcano in a land of ice is a scientific wonder.
