The Rodman series consists of excessively drained soils that formed in loamy and gravelly outwash overlying calcareous, stratified sandy and gravelly outwash. They are very deep soils that are shallow to the calcareous, stratified sandy and gravelly outwash. The Rodman soils are on kames, eskers, moraines, outwash plains, and valley trains.
Permeability is moderately rapid in the solum and very rapid in the substratum.
Slopes range from 2 to 70 percent. 40 degrees 15 minutes 28.78 seconds N, and long. The depth to the base of soil development ranges from 10 to 20 inches and is the same as the depth to carbonates. The A horizon has hue of 7.5YR or 10YR, value of 2 or 3, and chroma of 1 or 2. It is gravelly loam, loam, gravelly coarse sandy loam, gravelly sandy loam, or sandy loam.
