Minnesota Geological Survey (MGS) and Minnesota Geospatial Information Office (MnGeo)This layer describes the general distribution of surficial sediments in Minnesota, as delineated and classified by the Minnesota Geological Survey. It is a digital version of the Minnesota Geological Survey State Map Series Map S-1 (Geologic Map of Minnesota: Quaternary Geology), 1982, by H.C. Hobbs and J.E. Goebel. (1:500,000). The digital file was created by scanning the 1:500,000-scale paper map and then converting the scanned image into an Arc/INFO polygon coverage. In 2008 MGS converted the original linework to a shapefile format and added more descriptive fields based on the Quaternary Geology Code. File geodatabase format was created for the Minnesota Geospatial Commons. To produce a general descriptive layer of quaternary (surficial) geology for the state.Map was delineated in 1982 based on the information available at the time.Filesgeos-quaternary-geology-mnengPublicGeologic Map - Quaternary Geology, (MGS Map S-1), 1982 [Minnesota]DatasetsMinnesotaMinnesota Geospatial Commons
