TYPE LOCATION: Mackinac County, Michigan; about 3 miles southeast of Gould City; 300 feet east and 1,100 feet north of the southwest corner, sec. 10, T.42 N., R.11 W.
RANGE IN CHARACTERISTICS: (Unless otherwise stated the depths in the following paragraph are measured from the mineral soil surface.) Solum thickness and depth to carbonates ranges from 30 to 61 centimeters. Gravel content ranges from 1 to 10 percent in the solum and 25 to 40 percent in the substratum. Cobble content ranges from 5 to 20 percent throughout the pedon. The fine earth fraction of the particle control section ranges from 2 to 10 percent clay and contains between 50 and 70 percent fine sand or coarser.
Some pedons have an A horizon with hue of 5YR to 10YR or is neutral, value of 2 or 3, and chroma of 0 to 2. It is fine sandy loam, sandy loam, or cobbly analogs of these textures. Reaction of the A horizon ranges from strongly acid to moderately acid.
The E horizon has hue of 5YR or 7.5YR, value of 4 to 6, and chroma of 1 or 2. It is sandy loam, fine sandy loam, loamy fine sand, or cobbly analogs of these textures. Reaction is strongly acid or moderately acid.
The Bhs horizon has hue of 5YR or 7.5YR and value and chroma of 2 or 3. It is fine sandy loam, sandy loam, or the cobbly analogs of these textures. Reaction is strongly acid or moderately acid.
The Bs horizon has hue of 5YR or 7.5YR, value of 3 or 4, and chroma of 4. It is sandy loam, fine sandy loam, loamy sand or the cobbly analogs of these textures. Reaction is strongly acid to slightly acid.
Some pedons have a BC horizon with hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 to 6. It is loamy sand or sandy loam, or the gravelly or cobbly analogs of these textures.
The Cd horizon has hue of 10YR or 7.5YR, value of 5 to 7, and chroma of 3 or 4. It is the very gravelly analogues of sandy loam or fine sandy loam. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: There are no other series in the same family.
GEOGRAPHIC SETTING: The Cozy soils are on level to undulating slopes of ground moraines and drumlins. Slopes range from 0 to 6 percent. Mean annual precipitation ranges from 710 to 810 millimeters and mean annual temperature ranges from 5 to 6 degrees C.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Wallace, Amadon and the Battydoe soils. The Wallace soils formed in very deep sands. The Amadon soils are underlain by limestone bedrock at 25 to 51 centimeters. The Battydoe soils do not have dense till.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. These soils have a perched wet soil moisture status above the dense till that ranges from 30 to 46 centimeters below the surface during the months of January, February, and April. Saturated hydraulic conductivity is moderately high or high in the solum and low or moderately low in the substratum. Surface runoff is slow.
USE AND VEGETATION: Most areas are forested. Common trees are sugar maple, American beech, white ash, American basswood, quaking aspen, paper birch, and balsam fir.
DISTRIBUTION AND EXTENT: Eastern end of the Upper Peninsula of Michigan. This series of small extent.
