History

Frosty Peak is the tallest and most recently formed peak of the volcanic complex.[3] Its exact age is unknown, but it was probably formed in the middle to late Pleistocene, and possibly erupted even more recently. Frosty Peak is the southern cone of the double-coned Frosty Volcano, which formed in the middle Pleistocene some time before the Wisconsin Glaciation.[4]

Frosty Volcano itself is located on the northern flank of an even older volcano, the Morzhovoi Volcano.[5] Morzhovoi Volcano was probably formed in the early to middle Pleistocene, and collapsed into a caldera. The highest points that remain from the caldera are called North and South Walrus Peak.[6]
