Takawangha

Stratovolcano · United States · 1449m

Takawangha is seen here looking E from the summit of East Tanaga. It lies across a saddle from historically active Tanaga volcano to the west. The summit has five Holocene craters that produced explosive eruptions and lava flows that reached the lower flanks during the last few thousand years.

Geological summary

Takawangha is a youthful volcano with an ice-filled caldera on northern Tanaga Island, near the western end of the Andreanof Islands. It lies across a saddle from historically active Tanaga volcano to the west; older, deeply eroded volcanoes lie adjacent to the east. The summit of the dominantly basaltic to basaltic andesite volcano is largely ice covered, with the exception of five Holocene craters that during the last few thousand years produced explosive eruptions and lava flows that reached the lower flanks. No historical eruptions are known, although radiocarbon dating indicates explosive eruptions have occurred within the past several hundred years.

From Wikipedia

Mount Takawangha is a stratovolcano located in Tanaga Island, Alaska. It sits in close proximity with another volcano known as Mount Tanaga, which shares the same name as the island itself. Older and more eroded volcanoes can also be found east of Takawangha. Its elevation is 4,754 ft, making it the second-highest peak on the island.
