From Smithsonian Institution, Global Volcanism Program online database, accessed December 8, 2003: "Takawangha is a 1449-m-high, youthful volcano with an ice-filled caldera on northern Tanaga Island, near the western end of the Andreanof Islands. Takawangha lies across a saddle from historically active Tanaga volcano to the west; older, deeply eroded volcanoes lie adjacent to Takawangha on the east. Numerous small post-caldera tephra cones are located within the caldera and on its rim and flanks. The youngest cones are some of those inside the caldera of the basaltic-to-dacitic volcano. No historical eruptions are known from Takawangha."
