Additional Acknowledgments: Geology modified from Schmoll and Dobrovolny (1972). Digital cartography by R.A. Combellick and S.M. Weems, with suggestions by A.L. Schell. R.D. Reger and P.J. Haeussler provided helpful comments on the draft map and cross sections.\r\nMicrosoft Windows XP SP2, ArcGIS 9.+, and any text editor.\r\n\r\n\r\n\r\nThe "ak_volccent" data was created by digitizing points from a paper copy of U.S. Geological Survey Map I-1091-F, showing distributions, composition and age of late Cenozoic volcanic centers in Alaska. Coverages were created using Arc/Info 7.0.4, distributed by ESRI, Inc. Locations of volcanoes were acquired from latitude and longitude points found in Luedke and Smith (1990) and Wood and Kienle (1990), although errors may exist. The points were entered into a spreadsheet and e00 coverages were created using GIS software. The structural lines on the map may have been digitized into a GIS environment using data from Plafker and others (1994) and Moore (1992), or an unknown source.\r\n\r\nPolygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships.\r\nThis data set includes locations of volcanoes and volcanic centers in Alaska as of 1998.
