This wave-cut section exposes the interior of the Burr Point debris-avalanche deposit from the 1883 eruption of Augustine volcano. The different colors resulting from the transport of discrete segments of the volcano that are not thoroughly mixed are a characteristic appearance of debris avalanche deposits. The scale bar is 2 m high.
