It consists of a roughly circular cone approximately 3 km in diameter with a lake-filled central crater that is 1.2 km in diameter and extends from the highest point on the island to sea level. The oldest unit recognized is a thick series of mid-Pleistocene glaciovolcanic deposits consisting of autobrecciated lava, lahars, and volumetrically minor lava masses that we believe to have been emplaced underneath a regional ice cap. This unit is unconformably overlain by several massive Holocene lavas, above which lies a thick sequence of latest-Holocene pyroclastic deposits likely deposited during the crater-forming eruption. The 2008 eruption enlarged the preexisting crater, and produced pyroclastic density currents, surges, and fall that blanketed the entire island except for the crater wall and steep, seaward-facing cliffs on the flanks. 2008 deposits initially extended the shoreline seaward by up to 500 m. Kasatochi lava and scoria are porphyritic basalt, basaltic andesite, and andesite, all of which bear trace-element evidence for prolonged crustal residence and equilibration with an amphibole-rich gabbroic residue. Lavas from individual effusive eruptions have limited compositional range, whereas juvenile scoriae from explosive eruptions span the majority of the compositional range of the entire volcano. 2008 pyroclastic deposits contain texturally diverse amphibole gabbro clasts and smaller, less abundant, plagioclase-free pyroxenitic and peridotitic cumulate inclusions. We infer that the gabbroic inclusions are from the margins of regions of crustal magma storage and evolution and that equilibration with the amphibole plays an important role in the evolution of mafic and intermediate magmas.\nKasatochi is a small, isolated island volcano in the center of the Aleutian Island chain. It consists of a roughly circular cone approximately 3 km in diameter with a lake-filled central crater that is 1.2 km in diameter and extends from the highest point on the island to sea level. A large eruption in 2008 blanketed the island in pyroclastic deposits. 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 1:5000 scale geologic map and accompanying report is the first to document the geology of the entire island and it presents a snapshot of the island early in its response to the 2008 eruption. Map units are the result of combined field observations, aerial imagery interpretation, geochemical and geochronological analysis.\n\nThis digital data distribution package provides shapefiles and geodatabase that portray features presented in PR 123.

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.

All polygon features were topologically validated using ArcGIS prior to export to shapefile format.\nThis DGGS Professional Report is a final report of scientific research. It has received technical review and may be cited as an agency publication. This publication provides information about the mapped and interpreted geologic deposits distinguishable at a scale of about 1:5,000.

Data fields within each table record the author's degree of confidence in the location of applicable features.\n\n\n\n\nField data collection - Geologic field mapping and sampling were conducted during short trips on 18 days-nominally 2 to 3 days in mid-June and mid- to late-August-from 2009 through 2013. In addition to other field observations, we captured high-resolution panoramic photographs of the island flanks taken from offshore and of the crater wall taken from the rim.\n2013\n\n\nRock sample analysis - More than 110 rock samples were collected during the course of mapping. One hundred one of these samples were analyzed for major and trace elements by the Peter Hooper GeoAnalytical Lab at Washington State University. Detailed petrographic descriptions and 1,000-point modes were made using thin sections of 67 of the samples. Electron probe microanalysis (EPMA) at the Advanced Instrumentation Laboratory at the University of Alaska Fairbanks produced 3,364 mineral analyses, including core-rim pairs from 1,385 grains, from 24 representative samples, spanning all lithologic units. In addition, 40Ar/39Ar ages were obtained for three samples by the USGS, Menlo Park, California.\n2015\n\n\nTechnical review - This is a final report of scientific research.
