These are the Cruze , Donlonton , Flatwoods , Keyport and Latham series in the same family. The Cruze soils formed in colluvium or residuum and typically contain more than 3 percent sandstone rock fragments in the control section. Donlonton soils formed in old marine sediment on the Northern Atlantic Coastal Plain, contain moderate amounts of glauconite in the profile, and have texture of sandy clay or sandy clay loam in the Bt horizon. Flatwoods soils is moderately deep to shale bedrock and formed in residuum. Keyport soils formed in Coastal Plain sediments and allow hue of 2.5Y and 5Y in the solum.
Latham soils are moderately deep to a paralithic contact and formed in residuum.
The Licking , Tygart and Vincent series are in similar families. Licking and Vincent soils have base saturation greater than 35 percent at 50 inches below the top of the argillic horizon. The Tygart soils have evidence of wetness immediately below the Ap horizon. The Zoar soils are on terraces. They formed in acid slackwater sediments.
