Frosty Peak Volcano

Frosty Peak Volcano, a 6,299-foot stratovolcano at the southwest end of the Alaska Peninsula, is the highest, tallest, and most recently formed peak in its local volcanic complex. Also called Mt. Frosty, Frosty Volcano, or Cold Bay Volcano, it probably formed in the middle to late Pleistocene and may have erupted more recently, though its exact age is unknown. Frosty Peak makes up the southern cone of the double-coned Frosty Volcano, which developed before the Wisconsin glaciation. This volcanic system rises on the northern flank of older Morzhovoi Volcano, whose collapse created a caldera now marked by North Walrus Peak and South Walrus Peak.
