A massive flank collapse of on older Shishaldin volcano edifice caused these large blocks to tumble down the side of the mountain, sometime in the early Holocene. The event created a debris field covering an area of over 2,000 acres (~3.7 square miles or miles or ~9.6 square kilometers) and extending ~7 miles (~11 km) from the source on the upper flanks.
