Frosty Volcano
Encyclopedia
Frosty or Mt. Frosty is a stratovolcano
and the westernmost Holocene
volcano of the Alaska Peninsula
in Alaska, USA. Frosty is the youngest of the two large volcanic structures of the Cold Bay
volcanic complex. It has a summit elevation of 6601 feet (2,012 m). Frosty's last known eruption is unknown. The oldest products of the roughly 100 cu km Cold Bay complex, which lies southwest of the village of Cold Bay
, form the glacially dissected late-Pliocene to early Pleistocene Morzhovoi Volcanics at the southern end of the complex.
to Recent stratovolcano constructed within the southernmost 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 at 600 m (1,969 ft) above the floor of the southern crater.
Stratovolcano
A stratovolcano, also known as a composite volcano, is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions...

Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...
