Report on methods and results of geological investigations in the Pearl Lake study area in St. Louis County, Minnesota. Notes, diagrams, and interpretations in this report are a record of work done by geologists of the Minnesota Geological Survey under the terms of a contract between the Minnesota Geological Survey and the Minnesota Waste Management Board. Because the contract was terminated prior to project completion, no final report was issued. The materials in this notebook should be construed as preliminary findings that have not been reviewed for technical content or conformity to editorial standards of the Minnesota Geological Survey.
