TYPE LOCATION: Mackinac County, Michigan; about 5.5 miles south of Gould City; 1,800 feet south and 50 feet east of the northwest corner, Sec. 27, T. 42 N., R. 11 W.
RANGE IN CHARACTERISTICS: The depth to limestone bedrock ranges from 10 to 20 inches. Reaction is strongly acid or moderately acid throughout. Limestone cobbles and channers range from 0 to 20 percent by volume and commonly are on the surface and mixed throughout the profile. Limestone gravel content ranges from 0 to 14 percent throughout the profile. Clay content ranges from 2 to 12 percent.
The A horizon, where present, has hue of 7.5YR, 10YR or is neutral with value of 2 or 3 and chroma of 0 to 2. It is sandy loam, fine sandy loam, very fine sandy loam, silt loam or the gravelly, cobbly or channery analogues of these textures.
The E horizon has hue of 5YR or 7.5YR, value of 5 or 6 and chroma of 1 or 2. It is loamy very fine sand, sandy loam, fine sandy loam, very fine sandy loam, silt loam or the gravelly, cobbly or channery analogues of these textures.
The Bhs horizon has hue of 5YR or 7.5YR and value and chroma of 2 or 3. It is loamy very fine sand, sandy loam, fine sandy loam, very fine sandy loam, silt loam or the gravelly, cobbly or channery analogues of these textures.
The Bs horizon has hue of 7.5YR or 5YR, value of 3 or 4 and chroma of 4 to 6. Where there is no Bhs horizon the Bs horizon has hue of 7.5YR or 5YR, value of 3 or 4, and chroma of 4. It is loamy very fine sand, sandy loam, fine sandy loam, very fine sandy loam or the gravelly, cobbly or channery analogues of these textures.
COMPETING SERIES: These is the Freda series. Closely related are the Creasey, Hogback, Lyman, Monson, and Peshekee series. The Freda soils have a paralithic contact and formed over siltstone or shale bedrock. The Peshekee soils have semiactive clay mineralogy and are underlain by igneous or metamorphic bedrock. The Creasey, Hogback, Lyman and Monson soils have isotic mineralogy. In addition, the Creasey soils have rock fragments derived from sandstone. Hogback soils contain rock fragments derived from schist, gneiss, phyllite or granite and have Bhs horizons greater than 4 inches thick. Lyman soils have coarse fragments derived from schist and phyllite. Monson soils have yellower hues in the lower part of the profile and have coarse fragments derived from slate , phyllite or schist.
GEOGRAPHIC SETTING: Amadon soils are on ground moraines and bedrock benches. Slope gradients range from 0 to 45 percent. Mean annual temperatures range from 42 to 44 degrees F., and mean annual precipitation ranges from 28 to 32 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Battydoe, Furlong, Guardlake, Longrie and Shelter soils on similar landscape positions. The Battydoe, Guardlake and Shelter soils lack bedrock within 60 inches. Longrie soils are underlain by limestone bedrock at depths of 20 to 40 inches. Furlong soils are sandy and are underlain by limestone bedrock.at depths of 20 to 40 inches. Ensign soils are somewhat poorly drained and are located in slightly lower landscape positions.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is negligible to high, dependent on slope. Permeability is moderate.
USE AND VEGETATION: Most areas of this soil are forested. Vegetation consists of sugar maple, American beech, red maple, paper birch, quaking aspen, ironwood, balsam fir, red pine, eastern white pine and northern white cedar.
DISTRIBUTION AND EXTENT: Eastern and Central Upper Peninsula of Michigan. The series is of small extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are: ochric epipedon and albic horizon - the zone from 2 to 8 inches (E horizon); spodic horizon - the zone from 8 to 15 inches (Bhs and Bs horizons); lithic contact - limestone bedrock at 15 inches.
