Cabin Flat study area in Driftwood Bay, Umnak Island, Alaska

Along the northwestern shoreline of Driftwood Bay, Umnak Island, Alaska, the Cabin Flat study site (left) occupies a coastal lowland that backs a vegetated, emergent beach. Much of Driftwood Bay’s shoreline is flanked by sea cliffs over 50 m high and an extensive bedrock platform (right) in the intertidal zone. This site is referred to in the paper "Evidence for frequent, large tsunamis spanning locked and creeping parts of the Aleutian megathrust" for the project Alaska-Aleutian Subduction Zone Studies.
