TYPE LOCATION: Mackinac County, Michigan, about 2 miles northwest of the village of Engadine; 500 feet north and 250 feet east of the southwest corner of sec. 5, T. 43 N., R. 10 W.
RANGE IN CHARACTERISTICS: Solum thickness and depth to free carbonates ranges from 20 to 40 inches. Depth to the clayey material ranges from 12 to 32 inches.
The Ap horizon has hue of 7.5YR or 10YR and value of 2 or 3, and chroma of 2. The E horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 2 or 3. The A and E horizons are sandy loam or fine sandy loam. Reaction of the A and E horizons is slightly acid or neutral.
The Bhs horizon has hue of 5YR or 7.5YR, and value and chroma of 2 or 3. It is sandy loam, fine sandy loam, very fine sandy loam or loamy fine sand.
Where there is no Bhs horizon, the Bs horizon has hue of 7.5YR, value of 3 or 4 and chroma of 4. Where there is a Bhs horizon, it has hue of 7.5YR or 10YR, value of 3 or 4 and chroma of 4. It is sandy loam, fine sandy loam, very fine sandy loam, or loamy fine sand. Reaction of the Bhs horizon is moderately acid. The Bs horizon is moderately acid or slightly acid, but is always moderately acid in pedons that do not have a Bhs horizon.
Some pedons have E' horizons. Hue is 7.5YR or 10YR, value of 5 or 6, and chroma of 1 to 3. They are sandy loam, fine sandy loam, very fine sandy loam, or loamy fine sand. The loamy upper part of the soil averages from 4 to 12 percent clay and 50 percent fine sand or coarser.
The B part of the 2B/E horizon has hue of 5YR or 7.5YR and value of 4 or 5, and chroma of 4. It has textures similar to those of the 2Bt horizon. The E part of the 2B/E has hue of 7.5YR or 10YR, value of 5 to 7, and chroma of 2 or 3. It is loamy fine sand, fine sandy loam or silt loam. Reaction of the 2B/E horizon is slightly acid or neutral.
The 2Bt horizon has hue of 2.5YR to 7.5YR, value of 4 or 5, and chroma of 4. It is silty clay loam, silty clay or clay. Clay content of the argillic horizon ranges from 35 to 70 percent. Reaction of the Bt horizon is neutral or slightly alkaline.
The 2C horizon has hue of 2.5YR to 7.5YR, value of 4 to 6, and chroma of 3 or 4. It is silty clay or clay. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: This is the Sedgwick series. Similar soils are the Allendale, Biscuit and Fibre series. Allendale and Fibre soils are sandy over clayey. Biscuit soils are fine-silty over clayey. Sedgwick soils have coarse fragments in the lower part of the control section and are underlain by glacial till.
GEOGRAPHIC SETTING: Engadine soils formed in loamy lacustrine deposits and in the underlying clayey lacustrine sediments on low ridges and loamy smears on lake plains. Slope gradients range from 0 to 3 percent. Mean annual temperature ranges from 41 to 43 degrees F. Mean annual precipitation ranges from 28 to 32 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Allendale, Glawe, Gogomain, Ontonagon, Pickford, Pinconning, Rudyard and Superior soils. The Allendale soils are sandy over clayey. The Glawe, Pickford and Pinconning soils are poorly drained. The Ontonagon and Rudyard soils are clayey throughout. The well drained Superior soils and the poorly drained Gogomain soils form a drainage sequence with the Engadine soils.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The soil has a seasonal high water table that is perched at the contact between the loamy and clayey material and ranges from .5 to 1.5 feet below the surface at some time during the period from November to May. Runoff is slow. Permeability is moderate in the upper loamy part and very slow in the lower clayey part.
USE AND VEGETATION: Engadine soils are used for pasture, hay, small grain and woodland. Common tree species include red maple, paper birch, quaking aspen, balsam fir, white spruce and white pine.
DISTRIBUTION AND EXTENT: Eastern Upper Peninsula of Michigan. The Engadine series is of small extent.
