Chetomba, Madelia, Pella, Rushmore, and Wacousta soils contain carbonates at depths less than 40 inches. Dolbee and Elvira soils formed in silty alluvial sediments on flood plains and river terraces and are subject to flooding. Dolbee soils do not have stratification and typically have less sand in the substratum than the Drummer soils. Elvira soils have high concentrations of iron and manganese oxides in the solum. Dunham soils average more than 15 percent gravel in the lower part of the series control section.
Elpaso soils have a well graded sand fraction in the lower part of the series control section.
Garwin, Hartsburg, Mascoutah, Ossian, and Sable soils average less than 15 percent sand in the lower part of the series control section. Patton soils average less than 25 percent sand in the lower part of the series control section, and the sand fraction is dominantly fine and very fine sand. Drummer soils are on nearly level or depressional parts of outwash plains, stream terraces, and till plains of Wisconsinan Age. Slope ranges from 0 to 2 percent. Drummer soils formed in 40 to 60 inches of loess or other silty material and in the underlying loamy stratified outwash.
