bottom tiers. Silty clay loam overwash, clay loam substratum, marshy(ponded), and <br /> flooded phases are recognized in some places. <br /> The surface tier has hue of lOYR, 7.SYR, or neutral, value of 2 or 3 and chroma of 0 to 2. <br /> The herbaceous organic part of the subsurface and bottom tiers has hue of SYR, 7.SYR or <br /> lOYR or is neutral in hue. Value is 2 or 3 and chroma is 0 to 4. It is dominantly muck <br /> (sapric material), but some pedons have layers of mucky peat(hemic material) up to 10 <br /> inches thick. <br /> The Lco horizon has hue of lOYR, 2.SY, SY, or SGY,value of 2 to 5 and chroma of 1 to <br /> 3. It is coprogenous material. Iteaction ranges from neutral to moderately alkaline and <br /> carbonates are present in some pedons. The Lco horizon has slightly plastic consistence <br /> and shrinks upon drying to form hard clods that are difficult to re-wet. <br /> COMPETING SERIES: These are the Yloston and Toto series. Moston soils have sand <br /> below the limnic layer within the 51 inche control section. Toto soils have marl and sand <br /> below the limnic layer within the 51 inch control section. <br /> ' GEOGRAPHIC SETTING: The Muskego soils commonly are in depressional areas <br /> principally associated with glacial lake plains and flood plains, but other geographical <br /> locations are not excluded. Slope ranges from 0 to 2 percent. These soils formed in <br /> herbaceous organic material dominantly from grasses, sedges, and reeds over <br /> coprogenous limnic material(sedimentary peat). Mean annual temperature ranges from <br /> 46 to 52 degrees F. Mean annual precipitation ranges from 25 to 40 inches. The frost free <br /> period ranges from about 130 to 180 days. Elevation ranges from 679 to 1400 feet. <br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are the Hou�hton and Klossner <br /> series. Houghton soils are in nearby areas where the organic deposits are more than 51 <br /> inches thick and coprogenous material is not in the lower part of the control section. <br /> Klossner soils are in areas where the coprogenous material is absent and the herbaceous <br /> , organic material is underlain by loamy mineral material. <br /> � DRAINAGE AND PERMEABILITY: Very poorly drained. The potential for surface <br /> runoff is low or negligible. Permeability is moderate or moderately rapid in the <br /> herbaceous sapric material and slow in the coprogenous material (sedimentary peat). <br /> Most Muskego soils have an apparent water table from 1 foot above the surface to 1 foot <br /> below the surface in most years for much of the period from November to August. Some <br /> Muskego soils have an apparent water table from 3 feet to 1 foot above the surface in <br /> most years for much of the period from January to December. <br /> USE AND VEGETATION: Most areas remain in natural vegetation and provide <br /> wildlife habitat.Natural vegetation is dominantly grasses, reeds, and sedges with <br /> scattered hardwoods.A few areas have been drained and are used cropland. <br /> ' DISTRIBUTION AND EXTENT: Southern Wisconsin and southern Minnesota and in <br /> Illinois, Indiana, Iowa, and Ohio. MLRA 95B, 98, 102A, 103, 104, 105, 108, 110, 11 l, <br /> 114, and 144A. The Muskego soils are of moderate extent. <br /> MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana <br />
