It is very strongly acid to medium acid. The 3R horizon is hard sandstone. These are the Amanda , Belmont , Belmore , Chenault , Chili , Coggon , Conestoga , Douds , El Dara , Gallman , Grellton , Hayden , Hebron , Hickory , High Gap, Hollinger , Kalamazoo , Kanawha , Kendallville , Kidder , Kosciusko , LeRoy , Letort , Lindley , Mandeville , Martinsville , McHenry , Miami , Mifflin , Military , Norden , Ockley , Owosso , Pecatonica , Princeton , Rawson , Relay , Renova , Richland , Riddles , Rockbridge , Roseville, Sisson , Skelton , Strawn , Summitville , Teanaway , Theresa , Wawasee , Westville , Whalen, and Woodbine soils series. All these soils except Mandeville, Military, Norden, and Mandeville do not have bedrock above a depth of 40 inches. Mandeville soils have less sand in the solum and are formed in residuum from acid silty shale.
Military soils have more sand in the upper part of the solum.
Norden soils formed in glauconitic sandstone. Whalan soils have more clay and are less acid in the lower part of the solum formed from limestone. High Gap soils are on bedrock terraces. The slope gradient is O to 60 percent. High Gap soils formed in up to 20 inches of silty material and the underlying loamy Wisconsinan outwash.
