TYPE LOCATION: Mackinac County, Michigan; about 7 miles west of Gould City; 1,800 feet east and 50 feet south of the northwest corner. sec. 30, T.43 N., R. 12 W.
RANGE IN CHARACTERISTICS: (Unless otherwise stated the depths in the following paragraph are measured from the mineral surface.) Thickness of the loamy cap ranges from 5 to 15 inches. Depth to the calcareous sand and gravel ranges from 15 to 30 inches. Gravel content ranges from 0 to 15 percent in the solum and 25 to 50 percent in the substratum. Cobble content ranges from 0 to 5 percent in the solum and 1 to 10 percent in the substratum.
The A horizon has hue of 10YR, 7.5YR, or is neutral, value of 2 or 3, and chroma of 0 to 2. It is sandy loam or fine sandy loam. Reaction is strongly acid or moderately acid.
The E horizon has hue of 10YR or 7.5YR, value of 5 or 6, and chroma of 2 or 3. It is sandy loam or loamy sand. Reaction is strongly acid or moderately acid.
The Bhs horizon has hue of 5YR or 7.5YR, value and chroma of 2 or 3. It is sandy loam or fine sandy loam. Reaction is strongly acid or moderately acid.
The Bs horizons have hue of 7.5YR or 5YR, value of 3 to 5, and chroma of 3 or 4. They are loamy sand, sand, or the gravelly analogs. Reaction ranges from strongly acid to slightly acid.
Some pedons have a BC horizon with hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 4 to 6. It is sand or gravelly sand.
The 2C horizon has hue of 10YR, value of 5 or 6, and chroma 3 or 4. It is gravelly sand or very gravelly sand. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Chinwhisker, Croswell, Croswood, Cublake (T), Euclaire (T), Gilchrist, Halfaday, Manitowish and Mattix series. Chinwhisker soils have glossic E/Bt horizons within 40 inches. Eauclaire soils have a Bt horizon below the spodic horizon. Croswell, Croswood, Cublake, Gilchrist, and Halfaday 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 rock fragments in the C horizon. Manitowish soils do not contain free carbonates within a depth of 60 inches. Mattix soils are saturated within a zone from 0.5 to 1.5 feet at some time during the period from October to May.
GEOGRAPHIC SETTING: The Heinz soils are on nearly level to undulating slopes on outwash plains and ground moraines. Slopes range from 0 to 6 percent. Mean annual precipitation ranges from 28 to 32 inches and mean annual temperature ranges from 41 t 43 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Battydoe, Cozy, Guardlake, Markey, and Mattix soils. The well drained Guardlake and somewhat poorly drained Mattix soils form a drainage sequence with Heinz soils. Battydoe and Cozy soils are loamy. Markey soils are organic deposits.
DRAINAGE AND PERMEABILITY: Moderately well drained. These soils have an apparent seasonal water table that ranges from 2 to 3.5 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, red maple, sugar maple, white spruce, and balsam fir.
DISTRIBUTION AND EXTENT: Eastern end of the Upper Peninsula of Michigan. This series is of small extent.
