TYPE LOCATION: Luce County, Michigan; 2350 feet east and 2400 feet north of southwest corner of sec. 7, T.46N., R.8W.
RANGE IN CHARACTERISTICS: The depth to lamellae ranges from 20 to 28 inches and the solum depth ranges from 32 to 48 inches. The particle size control section averages less than 5 percent clay.
The E horizon has hue of 7.5YR or 5YR, value of 5, and chroma of 2 or 3. It is loamy very fine sand, very fine sandy loam or silt loam. Reaction is extremely acid to very strongly acid.
The Bhs horizon has hue of 7.5YR or 5YR, value of 2.5 or 3, and chroma of 2 or 3. It is very fine sandy loam or silt loam. Reaction is extremely acid to very strongly acid.
The Bs horizon has hue of 7.5YR or 5YR, value of 3 to 5, and chroma of 4 to 6. It is loamy very fine sand, very fine sandy loam or silt loam. Reaction is extremely acid to very strongly acid.
The Bw horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 4. It is loamy very fine sand or very fine sandy loam. Reaction is very strongly acid to strongly acid.
The E part of the E&Bt horizon has hue of 10YR or 7.5YR, value of 5, and chroma of 2 or 3. It is loamy very fine sand or very fine sandy loam. The Bt part has hue of 7.5YR or 5YR, value of 4 or 5, and chroma of 4. It is very fine sandy loam or silt loam. Reaction is very strongly acid to moderately acid.
The C horizon has hue of 7.5YR or 10YR, value of 5 or 4, and chroma of 4 or 6. It is stratified very fine sand, loamy very fine sand, or very fine sandy loam. Reaction is very strongly acid to moderately acid.
COMPETING SERIES: There are none. The closely related Islandlake series has a particle size control section texture that averages sand or loamy sand.
GEOGRAPHIC SETTING: Zandi soils are on lake plains. Slopes range from 1 to 75 percent. Mean annual precipitation ranges from 28 to 36 inches. Mean annual temperature ranges from 41 to 43 degrees F. Elevations range from 700 to 760 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Auger, Annanias, Hendrie, and Markey soils. The moderately well drained Auger soils are on a slightly lower landscape positions. The somewhat poorly drained Annanais and poorly drained Hendrie soils are on lower landscape positions. The very poorly drained Markey soils are in depressions.
DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderate. Surface runoff is medium to high, dependent on slope.
USE AND VEGETATION: Most areas of this soil are forested. Common trees are sugar maple, American beech, red maple, paper birch, quaking aspen, and eastern hemlock.
DISTRIBUTION AND EXTENT: Eastern Upper Peninsula of Michigan. This series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota.
SERIES ESTABLISHED: Luce County, Michigan; 2005. The source of the name is an old logging camp in Luce County.
REMARKS: Diagnostic horizons and features recognized in the pedon are: Albic horizon - the zone from 2 to 6 inches (E horizon); Spodic horizon - the zone from 6 to 12 inches (Bhs and Bs horizons); lamellae - the zone from 22 to 37 inches (E&Bt horizon).
