Siliceous pebbles range from 0 to 15 percent by volume. Reaction of the Bt1 horizon ranges from moderately acid to neutral. Bt horizons have colors in shades of brown, olive, and yellow with or without reddish redoximorphic features. The reddish features decrease with depth and range from none to a few below the Bt2 horizon. Gray iron depletions range from none to common below the Bt2 horizon.
Reaction ranges from slightly acid to moderately alkaline and is typically noncalcareous.
The BCtk horizon has matrix colors in shades of brown, olive, gray, yellow or the matrix is mottled with these colors or there are redoximorphic features, strata or fragments with these colors. Texture of the BCk is clay loam, or clay with or without weathered shale fragments, pockets of loamy materials, or strata of these materials interbedded. The Ck is in shades of brown, olive or gray. It is mainly shale or clayey siltstone stratified with soil material ranging from loam to clay. Silt and clay dominate the shale materials.
