The depth to bedrock and the paralithic contact ranges from 4 to 20 inches. Organic matter content ranges from 0.5 to 2 percent in the upper few inches and decreases rapidly and uniformly with depth. Rock fragments are typically less than 15 percent but may range from 0 to 35 percent flat channers or semirounded sandstone fragments. The mean annual soil temperature ranges from about 47 to 52 degrees F. EC is less than 2 mmhos throughout. The surface may be covered with a gravel or channery lag from colluvial action upslope.
Reaction ranges from mildly through strongly alkaline.
Calcium carbonate ranges from 1 to 5 percent with no continuous horizons of visible secondary accumulation. A thin Bw horizon may be present in some pedons. Reaction ranges from mildly alkaline through strongly alkaline. The Cr horizon consists of soft, calcareous sandstone interbedded with thin lenses of siltstone and shale. Thin, discontinuous lenses of hard sandstone occur in some pedons.
