iii INTRODUCTION

This Open-File Report lists U.S. Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys reports and maps on the geology, geophysics, and mineral and water resources of Alaska published or released to open files in 1981 and a few older reports that were missed when compiling earlier indexes of this series. The reports and maps are listed by the quadrangles (scale 1:250,000) into which Alaska has been subdivided for topographic mapping (p. 4). As these three agencies also issue reports and maps on other subjects, the following lists are selected in the sense that such documents are not included. In general the listed reports and maps bear a 1981 imprint date; most of those with earlier imprint dates actually were not delivered until 1981. Reports that deal with regional tectonic hypotheses, regional syn theses, Alaska as a whole, or with areas that cannot be indentified with a specific quadrangle are listed under Alaska - General, as are statistical presentations, indexes, and the like. Reports and maps that deal with offshore areas not within quadrangle boundaries are listed under Offshore Areas. The Alaska - General and Offshore Areas lists appear before the alphabetically arranged quadrangle listings. This index is intended to bring up to date the other indexes of this series, which are listed on p. 2-3. Other indexes in this series
