Timeline of development of Whisky talus, on northern Kasatochi Island. The talus was built on top of 2008 eruption deposits, becoming progressively larger over a period of a few years (bluffs immediately behind the beach are entirely 2008 deposits). The green bloom of guano-based algae first seen in August 2011 shows that the talus had been colonized by auklets, perhaps the same individuals that were displaced from Tundering talus. The yellow plus marks the same feature in each photograph. Two geologists sitting on the beach are circled in yellow. Photographs by Jeff Williams (USFWS) and Chris Nye. See http://doi.org/10.14509/29718 for additional details.
