In some pedons below a depth of 40 inches there are strata ranging from silt loam to fine gravel. It is massive or single grain, depending upon texture. Consistence ranges from loose to friable. The Lovewell series is currently the only other one in the same family. Lovewell soils have redox depletions below 16 inches from the mineral soil surface.
Cornish soils are on flood plains that are commonly in broad depressions.
Slope ranges from 0 to 2 percent. The soils formed in alluvial deposits of very fine sand and silt. Flooding frequency ranges from twice annually to once in 10 years. Overflow generally occurs during spring runoff and during heavy rains. The climate is humid and cool temperate.
