The Beech series consists of very deep, moderately well drained, moderate or moderately slowly permeable soils formed in mixed colluvium derived from sandstone, shale, and siltstone.
Beech soils are on footslopes and colluvial fans.
Slope ranges from 3 to 35 percent. Near the type location, the mean annual air temperature is about 56 degrees F. and the mean annual precipitation is about 42 inches. Thickness of the solum ranges from 40 to 60 inches. Depth to bedrock is greater than 60 inches. Drainage mottles with chroma of 2 or less are below the upper 10 inches of the argillic horizon, and within 36 inches of the soil surface.
