Frosty Peak Volcano, also known asMt. Frosty,Frosty Volcano, orCold Bay Volcano, is a 6,299 ft (1,920 m)stratovolcano at the southwest end of theAlaska Peninsula in theU.S. state ofAlaska.[1][2]
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 Pleistocene some 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]
