Resumen geológico

A small unnamed lava dome and an associated lava flow about 30 km E of Becharof Lake and 8 km NW of Alinchak Bay are not significantly modified by glacial erosion. Detterman et al. (1987) suggested a Holocene age for the small dome. Lava flows traveled a short distance to the north.
