BEDROCK GEOLOGIC MAP OF THE ARROWHEAD AREA, ST. LOUIS AND LAKE COUNTIES, MINNESOTA. Full set of digital files (GIS) and documentation can be found at the University of Minnesota.This Open-File Report (OFR) is a repository for on-going mapping in Lake and St. Louis counties that began in 2015 and will be largely completed by 2020. It contains preliminary bedrock and surficial geologic maps and associated products covering parts, and eventually all of the two counties. Because the counties are large, they have been divided for mapping purposes into subareas, each containing the name Arrowhead. Surficial maps are divided into 4 subareas referred to here as the Central (content prefixed “CA,” 2016, 2017); Southeastern (SeA, 2017, 2018); Southwestern (SwA), and Northern Arrowhead (NA) areas. Bedrock maps and associated files cover 3 subareas referred to as Central (CA, 2016); Southern (SA, 2017); and Northern Arrowhead (NA, 2018). Note that the boundaries of NA subareas differ somewhat between the surficial and bedrock maps. Products within this Open File Report include bedrock geologic maps, surficial geologic maps, bedrock topography and depth to bedrock maps, Quaternary stratigraphy, sand distribution models, corresponding GIS files, and other digital content. Ancillary files such as technical reports, geophysical imagery and models, and geochronologic data are included for bedrock mapping in the 3 bedrock subareas. Once these preliminary products are complete, the data and interpretations will be recombined into County Geologic Atlases that will supersede this OFR.

The bulk of the thin sections in the database are poorly located or not located at all, as they temporally span the entire history of the Minnesota Geological Survey. However many of the thin sections constructed since the 1970's can be fairly easily located via old field maps and notebooks on file at the Minnesota Geological Survey. Due to the overwhelming number of sections they have been located on an 'as-needed' basis, meaning that as we progress through different mapping project areas, every attempt was made to properly locate where the sample for the thin section was taken. Several hundred thin sections have been located, mainly in northeastern Minnesota in Cook and Lake Counties, in central St. Louis County, and Itasca County. All thin sections that were made since the advent of GIS and GPS are already located, having been stored with the data for individual mapping projects.
