Soil Pit #6 is located on the slope shoulder of the terrace located 8-10 meters from the Hartnett drive.  The pit is located 2 meters from a tree line composed of Aspen and Prickly Ash.  Vegetation surrounding pit 6 is comprised of mainly grassy forbs. Soils in this location are mapped as the Finchford Series in new soil map data (Meyer Personal Communication 2001), and as Hubbard Loamy Sand 6-12 percent slopes (HuC2), in the Dunn County Soil survey (ref).  Our soil description generally is consistent with The Finchford Series, but there are some discrepancies.  The Finchford Series has a plow zone within its first horizon ours did not.  Because of these discrepancies, we think the Soil Profile of Pit #6 is most consistent with the Hubbard Loamy Sand (HuC2) Series as described in the Dunn County Soil Survey (ref).  Similarities between soil characteristics we observed in the Pit #6 soil profile and the Hubbard Series description include:  both have lost original surface material due to erosion, surface area is very dark brown, large A horizons (roughly32 cm in depth), the C horizon is roughly the same depth, and both descriptions have the same parent material (outwash plains and stream terraces).
