LOCATION SATAGO MIEstablished Series
TAXONOMIC CLASS: Fine-silty, carbonatic, frigid Typic Hapludolls
TYPICAL PEDON: Satago silt loam - on a 4 percent north-eastern facing slope in a forested area. (Colors are for moist soil unless otherwise stated.)
Oi--2 to 0 inches; slightly decomposed forest litter.
A--0 to 4 inches; dark brown (7.5YR 3/2) silt loam, grayish brown (10YR 5/2) dry; moderate medium granular structure; friable; many fine and medium roots; about 1 percent gravel; neutral; clear wavy boundary. (3 to 7 inches thick)
BA--4 to 8 inches; reddish brown (5YR 4/3) and brown (7.5YR 4/4) silt loam; moderate medium subangular blocky structure; friable; many fine and medium roots; about 7 percent gravel; neutral; gradual wavy boundary. (2 to 6 inches thick)
Bw--8 to 12 inches; reddish brown (5YR 4/4) silt loam; moderate medium subangular blocky structure; friable; common fine roots; about 30 percent grayish brown (2.5Y 5/2) weathered shale fragments that are easily crushed and 3 percent gravel; slightly effervescent; moderately alkaline; gradual wavy boundary. (3 to 20 inches thick)
C--12 to 46 inches; reddish brown (5YR 4/3) silt loam; weak medium subangular blocky structure; firm; about 20 percent grayish brown (2.5Y 5/2) weathered shale fragments that are easily crushed and 3 percent shale gravel; slightly effervescent; moderately alkaline; gradual wavy boundary.
(20 to 40 inches thick)
2Cr--46 to 60 inches; grayish brown (2.5Y 5/2) soft shale; strongly effervescent; moderately alkaline.
TYPE LOCATION: Mackinac County, Michigan; about 3 miles northeast of Moran; 150 feet west and 200 feet south of the northeast corner of sec. 23, T. 42 N., R. 4 W.
RANGE IN CHARACTERISTICS: Depth to paralithic contact ranges from 40 to 50 inches. The solum ranges from 10 to 30 inches thick. Thickness of the glacial till deposit ranges from 5 to 12 inches thick. Gravel content ranges from 0 to 10 percent throughout. Soft shale fragments that are easily crushed ranges from 0 to 12 percent in the A and BA horizon and from 3 to 30 percent in the Bw and C horizons. Weighted average calcium carbonate equivalent ranges from 40 to 70 percent.
The A horizon has hue of 7.5YR or 10YR or is neutral, value of 2 or 3, and chroma of 0 to 2. It is silt loam, loam, silty clay loam, or very fine sandy loam. Reaction ranges from neutral to moderately alkaline.
The BA and Bw horizons have hue of 5YR to 2.5Y; value of 3 to 5; and chroma of 2 to 4. They are silt loam, loam, or silty clay loam. Reaction of the Bw horizon is slightly or moderately alkaline.
The C horizons have hue of 5YR to 2.5Y; value of 3 to 6, and chroma of 2 to 6. They are silt loam, loam, or silty clay loam. Reaction is moderately alkaline.
COMPETING SERIES: There are no other series in the same family. Closely related are the Emmet and Onaway series. Emmet and Onaway soils do not have bedrock within 60 inches, have mixed mineralogy and have argillic horizons.
GEOGRAPHIC SETTING: Satago soils formed in loamy glacial drift and in the underlying soft calcareous shale over shale bedrock on ground moraines, lake plains or outwash plains. Slope gradients range from 0 to 12 percent. Mean annual temperature ranges from 41 to 43 degrees F, and mean annual precipitation ranges from 28 to 31 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Angelica, Greylock (T) and Search series. Angelica soils are poorly drained and are in slightly lower landscape positions. Search soils are somewhat poorly drained and are slightly lower landscape positions. Greylock do not have mollic epipedons and are on similar landscape positions.
DRAINAGE AND PERMEABILITY: Well drained. Surface runoff is slow to medium. Permeability is moderate.
USE AND VEGETATION: Most areas of this soil are forested. Overstory vegetation consists of sugar maple, quaking aspen, balsam fir, yellow birch, American basswood, and white ash. Some of the common forest understory vegetation includes sugar maple, sweet cicely, spinulose woodfern, ladyfern, Canada white violet, smooth yellow violet, Canada mayflower, false-Solomons-seal and wild leek.
DISTRIBUTION AND EXTENT: Eastern Upper Peninsula of Michigan. The Satago series is small in extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the mineral surface to 4 inches (A horizon); cambic horizon - the zone from 4 to 12 inches (Bw1 and Bw2 horizons).
