These are the competing Channahon , Dinsdale , Mendota , and Tama soils, and the Knowles soils. Channahon soils are on nearby areas where depth to bedrock is less than 20 inches. Where the loess is 20 to 40 inches thick over loamy till, the Dinsdale soils are nearby. Mendota soils are on areas next to Ripon soils where depth to limestone is greater than 60 inches and the solum formed in highly calcareous glacial till. In areas where the loess is thicker than 60 inches or no part of the sola formed in till, the Tama soils are nearby on similar slopes.
Surface runoff is medium.
Permeability is moderate. Some areas are in pasture. Native vegetation was prairie grasses with a few bur oak. This series is of minor extent. Columbia County, Wisconsin, 1972.
