The recent history of Augustine has been characterized by repetitive collapse of the summit area, producing debris avalanches that often reached the sea on all sides of the island, forming rocky deposits. This gully near the east shoreline exposes one such debris avalanche deposit. The Northeast Point debris avalanche deposit forms the headland in the distance.
