History
[edit]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 latePleistocene,and possibly erupted even more recently. Frosty Peak is the southern cone of the double-coned Frosty Volcano, which formed in themiddle Pleistocenesome time before theWisconsin 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 acaldera.The highest points that remain from the caldera are called North and South Walrus Peak.[6]
