Gilpin channery silt loam - cultivated. Solum thickness ranges from 18 to 36 inches. Fractured, bedded and rippable bedrock is at depths of 20 to 40 inches. Rock fragments are mostly angular to subangular channers of shale, siltstone and sandstone and comprise 5 to 40 percent of individual horizons of the solum and 30 to 90 percent of the C horizon. The rock fragment content is less than 35 percent, by volume in the upper 20 inches of the argillic horizon.
Reaction ranges from strongly to extremely acid throughout unless limed.
The clay mineralogy is mixed, with illite dominant and kaolinite and vermiculite in lesser quantities. Undisturbed pedons have a thin dark A horizon underlain by a 2 to 5 inch thick grayish brown E horizon. The Ap horizon has hue of 10YR with value of 3 through 5, and chroma of 2 through 4. Dry values are 6 or 7. The A horizon is silt loam or loam in the fine-earth fraction.
