C3--35 to 49 inches; stratified dark reddish brown (2.5YR 3/4) and reddish brown (5YR 4/4) fine sandy loam and fine sand; massive; very friable; common fine and medium roots; thin lenses (< 1 inch) of loam; few fine distinct dark reddish gray (5YR 4/2) redox depletions; many coarse distinct yellowish red (5YR 4/6) and few fine distinct red (2.5YR 4/6) iron accumulations in the matrix; moderately acid; clear wavy boundary.
C4--49 to 80 inches; stratified reddish brown (5YR 4/4) and reddish brown (2.5YR 4/4) loamy fine sand, sand, and fine sandy loam; massive; friable; few fine and medium roots; several thin lenses (< 1 inch) of silt loam and loam containing organic materials; 3 inch band of very gravely coarse sand from 66 to 69 inches; many medium and coarse distinct yellowish red (5YR 4/6) and few fine distinct dark red (2.5YR 3/6) iron accumulations in the matrix and along pores; common coarse distinct dark reddish gray (5YR 4/2) iron depletions in the matrix: strongly acid.
TYPE LOCATION: Bayfield County, Wisconsin; about 2.5 miles west and 7.5 miles north of Iron River; 20 feet north and 400 feet east of the southwest corner of section 35, T. 49 N., R. 9 W.; Iron River Watershed; USGS Blaine Creek WI topographic quadrangle; lat. 46 degrees 40 minutes 33 seconds N. and long. 91 degrees 28 minutes 03 seconds W., NAD 27.

Cobble content: 0 to 15 percent by volume, throughout
Gravel content: 0 to 15 percent by volume, throughout
Saturation: 6 to 30 inches for 1 month or more in most years
A horizon:
Hue: 5YR or 7.5YR
Value: 2 or 3
Chroma: 1 to 3
Texture: fine sandy loam
Reaction: strongly acid to slightly acid
Thickness Range: 3 to 7 inches
C horizon:
Hue: 2.5YR or 5YR
Value: 3 or 4
Chroma: 2 to 4
Texture: stratified textures of sand; loamy sand; fine sand; loamy fine sand; fine sandy loam; very fine sandy loam; loam and silt loam; very thin strata of silty clay loam, clay loam, or sandy clay loam occur in some pedons. The finer textured stratifications are the thinnest strata. The sand content of any of the stratified layers is always greater than 40 percent, and the weighted average sand content is always above 70 percent. Very fine sand is abundant, but is never greater than 40 percent of the sand fraction. Clay content is usually about 5 to 10 percent, except it may be higher in thin or very thin layers.
Redoximorphic features: Redox depletions above 20 inches
Reaction: moderately acid to slightly alkaline
