They formed in herbaceous organic material 16 to 51 inches thick overlying loamy glacial deposits on ground moraines, end moraines, outwash plains, lake plains, stream terraces, and flood plains. Permeability is moderately slow to moderately rapid in the organic material and moderately slow or moderate in the loamy material. Slopes range from 0 to 2 percent. Mean annual precipitation is about 32 inches. The depth to the loamy C horizon ranges from 16 to 51 inches.
Fibers are dominantly herbaceous.
Some pedons have thin layers within the organic portion of the control section that are dominantly woody fiber. Woody fragments over 2cm in size comprise less than 15 percent of the organic material. In some pedons the value or chroma or both increases 1 or 2 units when exposed to the air. The organic portion of the control section ranges from pH 4.5 to less than pH 7.8 in calcium chloride and does not have free carbonates. Up to 4 inches of peat is on the surface in some pedons.
