TYPE LOCATION: Luce County, Michigan; 650 feet north of the southeast corner of sec. 17, T.48N., R.8W.
RANGE IN CHARACTERISTICS: The particle-size control section averages less than 5 percent clay. Reaction ranges from extremely acid to very strongly acid in the solum and very strongly acid to moderately acid in the substratum.
The E horizon has hue of 7.5YR, value of 5, and chroma of 2 or 3. It is silt loam or silt
The Bhs horizon has hue of 5YR or 7.5YR, value of 2.5 or 3, and chroma of 1 or 2.
The Bs1 horizon has hue of 5YR or 7.5YR, value of 3 or 4, and chroma of 4.
The Bs2 horizon has hue of 5YR or 7.5YR, value of 4 or 5, and chroma of 4 or 6.
The BC horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 3 or 4. It is very fine sandy loam or silt loam.
The C1 horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 3 or 4. It is stratified silt loam, silt, or very fine sandy loam.
The C2 horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 2 to 4. It is silt loam, very fine sandy loam or silt.
Sandy substratum phases are included in the range of this series.
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: Auger soils are on lake plains. Slopes range from 0 to 6 percent. Mean annual precipitation ranges from 710 to 910 millimeters. Mean annual temperature ranges from 5 to 6 degrees F. Elevations range from 213 to 231 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Annanias, Zandi, Hendrie, and Markey soils. The somewhat poorly drained Annanias and poorly drained Hendrie soils are on lower landscape positions. The well drained Zandi soils are on hills and ridges. The very poorly drained Markey soils are in depressions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. These soils have representative wet soil moisture status that ranges from 76 to 137 centimeters below the surface in October, November, March, April, May, and June. Saturated hydraulic conductivity is moderately high or high. Surface runoff ranges from negligible to medium, dependent on slope.
USE AND VEGETATION: Most areas of this soil are forested. Common trees are red maple, American beech, eastern hemlock, sugar maple, yellow birch, quaking aspen, balsam fir, and white spruce.
DISTRIBUTION AND EXTENT: Eastern and Central Upper Peninsula of Michigan. This series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota.

REMARKS: Diagnostic horizons and features recognized in the pedon are: Albic horizon - the zone from 5 to 13 centimeters (E horizon); Spodic horizon - the zone from 13 to 38 centimeters (Bhs and Bs horizons); Oxyaquic saturation.
