The Minvale series consists of very deep, well drained soils that formed in colluvium and the underlying residuum from cherty limestone. These soils are in coves and on foot slopes, benches and fans.
Permeability is moderate.
Slopes range from 2 to 45 percent. Solum thickness and depth to bedrock are more than 60 inches. Reaction is strongly acid or very strongly acid in each horizon except the surface layer is less acid where limed. Amount of fragments of chert in each horizon ranges from 15 to 35 percent except the A horizon may range as low as about 10 percent. It is silt loam, loam, cherty silt loam, cherty loam, or rarely cherty silty clay loam.
