  Description:
    Abstract:
      Using GIS overlay techniques, surface formations extracted from the Quaternary geology map were combined with soil texture groups that had been reclassified from the STATSGO data, based on the Michigan Soil Management Group protocol. The concatenated surface formations and generalized soil texture categories were grouped into glacial landsystems.
    Purpose:
      The appropriate characterization of the hydrogeological properties of the glacial deposits in Michigan required a suitable geologic framework in order to regionalize the various data that were created from the WELLOGIC data base. This need derives both from depositional facies differences and from spatial variations in deposit thicknesses. For example, an outwash sand and gravel deposit in a short-lived glacial spillway will typically be thin, while that found in a proglacial outwash plain that received sediments for a much longer period will be thick. The compiled geologic framework builds upon the Quaternary geology maps (Farrand and Bell, 1982a, 1982b), which were improved by blending their morphological information with lithological data from the STATSGO soil association data base using the glacial landsystems perspective, an holistic form of terrain evaluation that links surface geomorphology and subsurface materials in a landscape context.

    Process_Step:
      Process_Description:
        Reclassify the Quaternary geology maps (available in digital form) to extract just the surficial formations (i.e. moraine, till plain, outwash plain or lake plain). Four legend items on the Quaternary geology map ("Peat and muck", "Postglacial alluvium", "Artificial fill" and "Exposed bedrock surfaces") are not glacial surface formations per se and were coded <None> in the revised database. Two spatial edits were performed on the Quaternary geology map. All "Dune sand" polygons that did not share a boundary with the shoreline (i.e. inland dunes), as well as all "Water" polygons were flagged for removal. Using the Eliminate command in ArcGIS, the spaces originally occupied by the "inland dunes" and "Water" polygons were filled with the attribute of the adjacent formation with the longest common boundary. The "water" polygons were removed in order to avoid a difficult sliver polygon problem so that the water class from the STATSGO data (1:250,000) could be used.

    Process_Step:
      Process_Description:
        Determine the dominant texture of the soil association polygons in the STATSGO data. The dominate soil texture and soil drainage class for each STATSGO data base record (i.e. MUID) were joined to the STATSGO soils map to develop a STATSGO soil texture map and a STATSGO drainage map. The processing was based on the Michigan Soil Management Group (Mokma, Whiteside and Schneider, 1974) and the component percent fields in the joined STATSGO data base. The vector polygons in this grouped texture map were dissolved on their texture group code to simplify the map.

      Process_Description:
        Using GIS overlay techniques, surface formations extracted from the Quaternary geology map were combined with soil texture groups that had been reclassified from the STATSGO data, based on the Michigan Soil Management Group protocol. The concatenated surface formations - generalized soil texture categories were grouped into glacial landsystems, as follows:

        Surface formation - soil texture class = Glacial Landsystem Moraine - Coarse = Ice-contact Outwash Moraine - Medium = Ice-marginal Till Moraine - Fine = Ice-marginal Till Moraine - Muck = Ice-marginal Till Moraine - Shallow Soil Over Bedrock = Ice-marginal Till Lake Plain - Coarse = Lacustrine Coarse Lake Plain - Medium = Lacustrine Fine Lake Plain - Fine = Lacustrine Fine Lake Plain - Muck = Lacustrine Fine Till Plain - Medium = Lodgement Till or Fine Supraglacial Drift Till Plain - Fine = Lodgement Till or Fine Supraglacial Drift Till Plain - Muck = Lodgement Till or Fine Supraglacial Drift Till Plain - Coarse = Proglacial Outwash Outwash Plain - Coarse = Proglacial Outwash Outwash Plain - Medium = Proglacial Outwash Outwash Plain - Fine = Proglacial Outwash Outwash Plain - Muck = Proglacial Outwash Outwash Plain - Shallow Soil Over Bedrock = Proglacial Outwash Dune Sand = Coastal Dunes Thin to Discontinuous Glacial Till Over Bedrock - "Any Soil Texture Class" = Thin Drift over Bedrock Lake Plain - Shallow Soil Over Bedrock = Thin Drift over Bedrock Till Plain - Shallow Soil Over Bedrock = Thin Drift over Bedrock "Any Surface Formation" - Bedrock = Bedrock

        The final glacial landsystems map was created using the Dissolve command in ArcGIS on the "Ldsystem" field.
