Initial fieldwork was supported by the North Pacific Research Board (Project number: 923), the U.S. Fish and Wildlife Service, the Alaska Volcano Observatory, and the U.S. Geological Survey. Additional fieldwork was supported by AVO and the USFWS. We thank USFWS for continued encouragement and support. We especially thank Jeff Williams of the USFWS for sharing his deep knowledge of Kasatochi history, biology, and geography, and for his all-encompassing interest in Kasatochi science. Fieldwork was supported by the M/V Tiglax, under the able command of Captain Billy Pepper; we thank the captain and crew for comfortable and safe transport. We thank pilots Burke Mees, Jerry Morris, and Roger Clifford for taking and sharing oblique aerial photographs. Post-eruption scientific studies span a large range of biologic and geologic disciplines, and we thank the other scientists for rewarding and fruitful cross-fertilization. Chris Nye thanks Patricia Gallagher for help with ArcGIS during preparation of the map draft and for final cartography, and Nicole Kinsman for help with establishing the Kasatochi Mean Sea Level datum. Reviews by Brian Jicha and especially Michael Clynne substantially improved the report. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the State of Alaska or U.S. Government. The geologic map database was converted to GeMS, quality controlled, and then finalized by DGGS staff Wes Buchanan and Mike Hendricks.
Kasatochi volcano is located at the intersection of the flat, shallow Aleutian platform and the Bering slope rise, an area of high biologic productivity. As a result, the island hosts a large sea lion colony and nesting sites for hundreds of thousands of seabirds. A large eruption in 2008 blanketed the island in pyroclastic deposits, covering nesting sites and almost all existing vegetation. A multidisciplinary effort to document recovery of the ecosystem was initiated and this study of the geology of the island was undertaken as part of that effort. This study is the first to document the geology of the entire island, and presents a snapshot of the island early in its response to the 2008 eruption.
