DETOUR SERIES
The Detour series consists of very deep, somewhat poorly drained soils that are moderately deep to dense till. Detour soils formed in loamy till on ground moraines and glacial lake benches. Slope ranges from 0 to 6 percent. Mean annual precipitation is about 762 mm (30 inches), and mean annual temperature is about 6.1 degrees C (43 degrees F).
TAXONOMIC CLASS: Fine-loamy, mixed, active, frigid Aquic Eutrudepts
TYPICAL PEDON: Detour cobbly loam, on a 2 percent slope in a forested area. (Colors are for moist soil unless otherwise stated.)
Oe--0 to 5 cm (2 inches); black (10YR 2/1) partially decomposed leaf litter.
A--5 to 20 cm (2 to 8 inches); very dark grayish brown (10YR 3/2) cobbly loam, light brownish gray (10YR 6/2) dry; strong medium granular structure; friable; about 25 percent cobbles and stones of limestone and dolomite; neutral; gradual wavy boundary. [13 to 18 cm (5 to 7 inches) thick]
E--20 to 30 cm (8 to 12 inches); grayish brown (10YR 5/2) cobbly loam; moderate medium platy structure; friable; many medium prominent yellowish brown (10YR 5/6) masses of oxidized iron; about 25 percent cobbles and stones; neutral; clear wavy boundary. [0 to 13 cm (5 inches) thick]
Bw--30 to 56 cm (12 to 22 inches); dark yellowish brown (10YR 4/4) cobbly sandy clay loam; weak medium subangular blocky structure; firm; many fine distinct grayish brown (10YR 5/2) iron depletions; about 25 percent cobbles and stones; slightly alkaline; clear wavy boundary. [20 to 71 cm (8 to 28 inches) thick]
Cd--56 to 152 cm (22 to 60 inches); grayish brown (10YR 5/2) gravelly sandy loam; weak coarse subangular blocky fragments and a tendency toward platy orientation of fragments; very firm; many medium distinct dark yellowish brown (10YR 4/4) masses of oxidized iron; about 20 percent gravel, cobbles, and stones; strongly effervescent; moderately alkaline.

COMPETING SERIES: There are no other series in the same family.
GEOGRAPHIC SETTING: The Detour soils are on ground moraines and glacial lake benches. Slope ranges from 0 to 6 percent. They formed in loamy till. Mean annual precipitation ranges from 686 to 813 mm (27 to 32 inches). Mean annual temperature ranges from 5.0 to 7.2 degrees C (41 to 45 degrees F).
GEOGRAPHICALLY ASSOCIATED SOILS: The moderately well drained
Johnswood and poorly drained or very poorly drained
Hessel soils are in the same drainage sequence with the Detour soils.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Potential for surface runoff is low to high. Saturated hydraulic conductivity is moderately low. Permeability is slow.
USE AND VEGETATION: The major part is in second growth woodland. Native vegetation is principally northern white cedar, paper birch, yellow birch, black spruce, balsam fir, and beech. A small part has been cleared and is in permanent pasture. Many areas of this soil are used for recreation because of nearness to the Great Lakes.
DISTRIBUTION AND EXTENT: MLRAs 94B, 94C, and 96 in the northern part of the Lower Peninsula and eastern and southern part of the Upper Peninsula of Michigan along the Great Lakes. The series is of moderate extent.
