Tracylee and Wetterdon soils do not have carbonates and low chroma redox features within a depth of 40 inches. Vosburg soils do not have low chroma redox features within a depth of 40 inches and have a drier soil moisture control section. Woodly soils contain 18 to 27 percent clay in the series control section. Woonsocket soils contain 55 to 80 percent fine sand or coarser in the particle size control section. Slope gradients typically are 0 to 2 percent but range from about 0 to 6 percent.
Surfaces typically are plane or slightly concave.
These soils formed in loam or clay loam glacial till. The till commonly is mantled with local alluvium 1 to 3 feet thick. The mean annual air temperature ranges from 45 to 52 degrees F, and precipitation ranges from 17 to 26 inches. These are the Bonilla , Clarno , Crossplain , Davison , Dudley , Ethan , Houdek , Stickney , and Tetonka soils. Bonilla soils do not have an argillic horizon and are on similar landscapes.
