Bw1--10 to 46 centimeters; brown (7.5YR 4/4) channery sandy loam; weak fine subangular blocky structure; very friable; common fine and medium roots; about 25 percent sandstone channers; strongly acid; gradual wavy boundary. (25 to 50 centimeters thick)
2Bw2--46 to 61 centimeters; strong brown (7.5YR 4/6) very channery loamy sand; single grain; loose; about 38 percent sandstone channers and 13 percent sandstone flagstones; strongly acid; gradual wavy boundary. (13 to 38 centimeters thick)
2Cr--61 to 102 centimeters; strong brown (7.5YR 5/6) weakly cemented sandstone; strongly acid.

GEOGRAPHIC SETTING:
Parent Material--loamy slope alluvium over sandstone residuum and in the underlying sandstone
Landform--hills in bedrock controlled uplands
Geologic formation--Jordan sandstone
Elevation--290 to 335 meters
Mean annual air temperature--9 to 11 degrees C

GEOGRAPHICALLY ASSOCIATED SOILS:
These are the

Drainage classsomewhat excessively drained--a saturated zone does not occur within a depth of 1.8 meters during April to June in normal years
Saturated hydraulic conductivity--14.11-42.34 micrometers per second (moderately rapid) in the loamy slope alluvium, 42.34-141.14 micrometers per second (rapid) in the sandy residuum, and 1.41-4.23 micrometers per second
(moderately slow) or 4.23-14.11 micrometers per second (moderate) in the sandstone.

SERIES ESTABLISHED: Richland County, Wisconsin, 2002. Name comes from a road in
Richland County.
REMARKS:
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: The zone from 2 to 10 centimeters.
Cambic horizon: The zone from 10 to 61 centimeters.
Paralithic contact: The contact with sandstone at 61 centimeters.
The Jordan Formation is interstratified with finer strata in places. However, the loamy slope alluvium is not from this formation but rather from the mixing of the loess and mass wasting of the clayey pedisediment (Rountree) from the surrounding Oneota and Shakopee Formations, which dominate the area. The 5YR and 7.5YR hues are indicative of this material. The Basco series, which also is formed from the mass wasting of the clayey pedisediment, is mapped on the higher positions on the landscape.
