TYPE LOCATION: Mackinac County, Michigan; about 7 miles west of Gould City; 2,150 feet east and 900 feet north of the southwest corner, sec. 19, T. 43 N., R. 12 W.
RANGE IN CHARACTERISTICS: Thickness of the loamy cap ranges from 5 to 15 inches. Depth to the calcareous sand and gravel ranges from 15 to 25 inches. Gravel content ranges from 0 to 15 percent in the solum and 20 to 45 percent in the substratum. Cobble content ranges from 0 to 5 percent in the solum and 1 to 10 percent in the substratum.
Some pedons have an A horizon with hue of 10YR, 7.5YR, or is neutral, value of 2 or 3, and chroma of 0 to 2. It is sandy loam or loamy sand. Reaction ranges from very strongly acid to moderately acid.
The E horizon has hue or 7.5YR or 10YR, value of 5 or 6, and chroma of 2 or 3. It is sandy loam or loamy sand. Reaction ranges from very strongly acid to slightly acid.
The Bhs horizon has hue of 5YR or 7.5YR, value and chroma of 2 or 3. It is sandy loam or loamy sand. Reaction ranges from very strongly acid to moderately acid.
The Bs horizon has hue of 7.5YR, value of 3 or 4, and chroma of 4 to 6. It is loamy sand or sand. Reaction ranges from strongly acid to slightly acid.
Some pedons have a BC horizon with hue of 10YR, value of 4 or 5, and chroma of 3 or 4. It is loamy sand, sand, or the gravelly analogs of these textures.
The 2C horizon has hue of 10YR, value of 5 or 6, and chroma of 3 or 4. It is gravelly sand or very gravelly sand. Reaction ranges from slightly alkaline to moderately alkaline.
COMPETING SERIES: These are the Chinwhisker, Croswell, Croswood, Cublake (T), Eauclaire (T), Gilchrist (T), Halfaday, Heinz (T), and Manitowish (T) series. Chinwhisker, Eauclaire, Halfaday and Manitowish soils do not contain free carbonates within a depth of 60 inches, in addition Chinwhisker and Halfaday contain less than 15 percent rockfragments. Croswell, Croswood, and Cublake soils do not have textures of sandy loam or fine sandy loam within the upper 15 inches of the series control section and contain less than 15 percent of rock fragments in the C horizon. Gilchrist 2C horizons in calcareous coarse-loamy glacial till. Heinz soils are saturated with a zone from 2 to 3.5 feet below the surface at some time during the period from October to May.
GEOGRAPHIC SETTING: The Mattix soils are on level or nearly level slopes on outwash plains and ground moraines. Slopes range from 0 to 3 percent. Mean annual precipitation ranges from 28 to 32 inches and mean annual temperature ranges from 41 to 43 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cozy, Guardlake, Heinz, and Markey soils. The well drained Guardlake and moderately well drained Heinz soils form a drainage sequence with Mattix soils. Cozy soils are loamy. Markey soils formed in organic deposits.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. These soils have an apparent seasonal water table that ranges from .5 to 1.5 feet below the surface at times during the period from October to May. Permeability is moderately rapid in the loamy part and very rapid in the sands and gravel. Surface runoff is slow.
USE AND VEGETATION: Most areas are forested. Common trees are quaking aspen, paper birch, balsam fir, red maple, white spruce, northern white cedar, and sugar maple.
DISTRIBUTION AND EXTENT: Eastern end of the Upper Peninsula of Michigan. Series of small extent.

SERIES ESTABLISHED: Mackinac County, Michigan, 1994.
REMARKS: Diagnostic horizons and features recognized in the pedon: albic horizon - the zone from 3 to 5 inches (E horizon); spodic horizon - the zone from 5 to 24 inches (Bhs, Bs horizons); oxyaquic subgroup - the soil is saturated with water in one or more layers within 40 inches of the surface in 6 out of 10 years.
