Frosty
About Frosty
Frosty Peak, the youngest of two large volcanic structures of the Cold Bay Volcanic Center, is the westernmost Holocene volcano on the Alaska Peninsula, SW of the village of Cold Bay. This symmetrical late-Pleistocene to Recent stratovolcano is constructed within one of two coalescing craters. The western wall of the ice-filled northern crater is breached by a large valley glacier. The symmetrical summit cone rises about 600 m above the floor of the southern crater. The oldest products of the roughly 100 km3 Cold Bay complex form the late-Pliocene to early Pleistocene Morzhovoi Volcanics at the southern end. Morzhovoi is an extensively eroded basaltic-to-andesitic stratovolcano with long U-shaped valleys extending from a central caldera. Only remnants of the volcano remain, with isolated peaks, such as North and South Walrus Peaks, that are fragments of the original caldera rim.
