Individual subhorizons have clay content as low as 22 percent or as high as 37 percent. Reaction ranges from strongly acid to medium acid. The average clay content ranges from 37 to 45 percent and the average sand content ranges from 5 to 20 percent. Individual subhorizons have clay content as high as 50 percent. Coarse fragment content ranges from 1 to 15 percent dominantly gravel size chert and shale.
Reaction ranges from strongly acid to mildly alkaline.
These are the Blair , Fishhook , Freeburg , Geff , Glenford , Henshaw , Ingersoll , keene , Lykens , Muren , Sardinia , Stoy , Travilah , and Xenia soils. Except for the Keene and Travilah soils, these competing series do not have a lithic or paralithic contact within a depth of 60 inches. The keene soils have a maximum pH of less than 6.6 in the lower part of the series control section. The Travilah soils have coarse fragments of serpentine throughout the series control section. Appleriver soils are on unglaciated hillside benches and rounded ridgetops.
