| Abstract | The occurrence of ground water in Minnesota is related primarily to local geologic conditions that determine the type and properties of aquifers. This map divides the state into six ground water provinces based on bedrock and glacial geology. Within each province, ground-water sources and the availability of ground water for drinking water, industrial, and agricultural uses are similar. The map was created using pre-existing maps and professional judgement to define provinces of the state with unique combinations of bedrock and unconsolidated aquifer characteristics. |

| Lineage | The boundaries between Provinces 1 and 4, and Provinces 2 and 5 were created in ArcView by combining individual Paleozoic and Precambrian sedimentary map unit polygons from the Minnesota Geological Survey (MGS) Bedrock Geology of Minnesota (Morey, G.B., 2000, Geologic Map of Minnesota, Bedrock Geology: State Map Series S-20, scale 1:1,000,000). These boundaries represent the western edge of Paleozoic and Precambrian sedimentary bedrock formations in Minnesota. This map is a compilation of some larger scale maps with source scales ranging from 1:24,000 to 1:750,000. The boundary of Province 6 was digitized by Jim Berg from a rectified version of the MGS Minnesota Bedrock Hydrogeology map (Kanivetsky, R., 1978, Hydrogeologic Map of Minnesota, Bedrock Hydrogeology.: Minnesota Geological Survey State Map Series S-2, scale 1:500,000). These polygons are shown as a transparent stippled overlay on the original map. The boundary between Provinces 2 and 3 and Provinces 1 and 3 was digitized from a Minnesota Land Management Information Center (LMIC) digital version of the MGS Depth to Bedrock Map (Olsen, B.M., and Mossler, J.H., 1982, Geologic Map of Minnesota, Depth to Bedrock.: Minnesota Geological Survey State Map Series S-14, scale 1:1,000,000) using the 0-100 foot boundary. This line defines the province of southeastern Minnesota where thin unconsolidated sediments overlie Paleozoic bedrock aquifers. The boundary between Provinces 1 and 2 was interpreted from the MGS Scott and Dakota County Geologic Atlases (Balaban, N.H., and McSwiggen, P.L., 1982, Geologic Atlas of Scott County, Minnesota and Balaban, N.H., and Hobbs, H.C.,1990, Geologic Atlas of Dakota County, Minnesota.) Both of these atlases were published at 1:100,000. Scott County geologic cross sections and a diagramatic map of the St. Croix moraine from the Dakota County Atlas were used to delineate sandy unconsolidated sediments in Province 1 from the less sandy sediments of Province 2. The boundary between Provinces 4 and 5 was digitized by Jim Berg from a distinct surface elevation boundary evident on the Minnesota Digital Elevation Model (DEM). The DEM was produced by the Minnesota Department of Natural Resources in 2000 at a 30 meter sampling interval using a variety of production processes. The Province 4/5 boundary derived from the DEM defines areas within the Alexandria and Superior moraine complexes. The drift deposited by glacial advances from the northeast are generally sandier than drift deposited from northwest advances (Des Moines and Red River lobes). In addition, outwash associated with the Pomme de Terre, Chippewa, and the western Minnesota River, (boundaries from LMIC digital version of Kanivetsky, R. 1979, Hydrogeologic Map of Minnesota, Quaternary Hydrogeology: Minnesota Geological Survey State Map Series S-3, scale 1:500,000) were lumped with this province. The Quaternary Hydrogeology map shows that most of the extensive sand plains in the state are within the boundaries of the Alexandria and Superior moraine complexes. Most of the water table wells of the state are also in this area. The Cretaceous Bedrock polygon layer is unaltered from the Minnesota Geological Survey (MGS) Bedrock Geology of Minnesota (Morey, G.B., 2000, Geologic Map of Minnesota, Bedrock Geology: State Map Series S-20, scale 1:1,000,000). These polygons are shown in a dot pattern overlay. The Biwabik Formation, an iron ore deposit found in Itasca and St. Louis counties was taken from the Minnesota Geological Survey (MGS) Bedrock Geology of Minnesota (Morey, G.B., 2000, Geologic Map of Minnesota, Bedrock Geology: State Map Series S-20, scale 1:1,000,000). This polygon, which is located on the boundary between provinces 4 and 6, was added to Province 4 using a union function in ArcView. |
