Some pedons have a 2Btg, 2Bt, 2BCg, or 2BC horizon with hue of 10YR, 2.5Y, or 5Y, value of 4 to 7, and chroma of 1 to 4. Texture and reaction are similar to the Btg horizon. Rock fragments are primarily limestone or dolostone. Rock fragment content ranges from 2 to 14 percent. It has colors like the 2B horizon.
Texture is loam or clay loam.
Reaction is slightly alkaline or moderately alkaline. This is the Pewamo series. Pewamo soils do not have a lithic contact within 40 inches. Competing series may change as they are updated to the 8th Edition of Keys to Soil Taxonomy. The Calamine and Lippincott series have not been updated to the 8th Edition of Keys to Soil Taxonomy, but were competing series to Millsdale under previous taxonomic classification.
