The Lowell series consists of deep and very deep, well drained soils formed in residuum of limestone interbedded with thin layers of shale on upland ridgetops and sideslopes.
Permeability is moderately slow.
Slopes range from 2 to 65 percent. The thickness of the solum ranges from 30 to 60 inches. Depth to limestone or interbedded limestone, shale and siltstone bedrock ranges from 40 to 80 inches or more. The soil to a depth of about 30 inches, ranges from very strongly acid to slightly acid, and below 30 inches from strongly acid to mildly alkaline except the layer immediately above the bedrock ranges from medium acid to mildly alkaline. Content of fragments of limestone or siltstone range from 0 to 5 percent in the upper part of the solum, from 0 to 15 percent in the lower part and 1 to 50 percent in the C horizon.
