Larsen Bay (American Samoa)

The bay features a steep descent to depths exceeding 500 meters and is characterized by rich coral coverage and diverse marine species.

The unconsolidated ash and cinder deposits from Larsen Bay to Olotele Mountain provide essential geological insight into the region's formative processes.
