Abstract
This volume is a continuation of the annual United States Geological Survey (USGS) Circulars reporting results of work in progress on earth science investigations in Alaska. The series began in 1975 under the title "The United States Geological Survey in Alaska - Accomplishments during 19xx" and has continued since 1986 under the present title. The 40 short papers and the feature article presented here report on some of the geologic studies undertaken in Alaska during 1987 by the USGS, cooperating agencies, and universities.
