Newhouse soils formed in 20 to 40 inches of loess and in stratified loamy pedisediments derived from erosion of weathered sandstone, shale or limestone. Shelbyville soils contain more than 40 percent clay in the lower part of the series control section. Watkins soils formed entirely in silty alluvium and do not have a lithologic discontinuity. Yutan soils formed entirely in loess and do not have a lithologic discontinuity. Waubeek soils formed in 20 to 40 inches of loess and underlying glacial till.
Waubeek soils are on convex ridge summits and side slopes on uplands.
Slopes range from 0 to 14 percent. Elevation ranges from 650 to 1100 feet. F. Mean annual precipitation ranges from about 30 to 35 inches. Frost-free period ranges from 130 to 186 days. These are the competing Downs soils, and the Bassett , Dinsdale , Franklin , Racine , and Tama soils.
