Geologic map of the Makushin volcanic field, Unalaska Island, Alaska

Report of Investigation 97-20, Geologic map of the Makushin volcanic field, Unalaska Island, Alaska, covers most of the north end of Unalaska Island, which is the extent of the Quaternary Makushin volcanic field. This study emphasizes the Holocene-Pleistocene eruptive history of Makushin Volcano and its satellite vents. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2576.
