The purpose of this report is to summarize the status and results of field work and other research carried out by personnel of the Minnesota Geological Survey during the past year. In addition, summaries are presented for research financed mainly by other sources but supported by the Survey. The report supplements the annual newsletter, which contains outline maps showing the status of the State geologic (bedrock) map atlas and gravity programs and other data on Survey activities. An index map that shows the status of detailed geologic mapping in northeastern Minnesota is included in the report. Maps of areas of immediate interest to the mining industry will be placed in open files during the year, to make them available at the earliest possible time. A list of other maps and reports that are being prepared currently for publication is given in the 1969 Newsletter.
