LOCATION TROUT BAY MIEstablished Series
TAXONOMIC CLASS: Euic, frigid Lithic Haplosaprists
TYPICAL PEDON: Trout Bay muck, on a northeast-facing slope of 16 percent, in a forested area. (Colors are for moist soil unless otherwise stated.)
0a1--0 to 18 centimeters; black (10YR 2/1) broken face and rubbed muck; about 20 percent fiber, less than 5 percent rubbed; moderate medium granular structure; slightly sticky; strongly acid, (pH 5.5 in water); clear wavy boundary.
0a2--18 to 48 centimeters; black (10YR 2/1) broken face and rubbed muck; about 15 percent fiber, less than 5 percent rubbed; weak coarse subangular blocky structure parting to weak medium granular structure; slightly sticky; about 5 percent sand grains; moderately acid (pH 5.6 in water); abrupt smooth boundary.
2Cr--48 to 86 centimeters; olive yellow (2.5Y 6/6) and light brownish gray (2.5Y 6/2) weathered sandstone; massive; firm; slightly acid (pH 6.4 in water); abrupt smooth boundary.
2R--86 centimeters; sandstone bedrock.
TYPE LOCATION: Alger County, Michigan; about 2,128 feet east and 2,522 feet north of the southwest corner of sec. 25, T. 47 N., R. 20 W.; USGS Au Train topographic quadrangle; lat. 46 degrees 26 minutes 31 seconds N. and long. 80 degrees 45 minutes 12 seconds W.
RANGE IN CHARACTERISTICS: The depth to sandstone bedrock ranges from 41 to 130 centimeters. Woody fragments ranging in size from 2mm to 6 centimeters in diameter are at random throughout the control section and comprise 5 to 15 percent of the volume in some pedons. The surface and subsurface tier has hue of 10YR, 7.5YR or is neutral, value of 2 or 3, and chroma of 0 to 2. The reaction in the organic portion of the control section is very strongly acid to moderately acid.
The surface tier is dominantly sapric material with an unrubbed fiber content that ranges from 5 to 25 percent, and a rubbed fiber content of less than 5 percent. The structure is weak or moderate, fine or medium granular. In some pedons the upper 8 centimeters of the surface tier is mucky peat.
The subsurface tier is sapric material with an unrubbed fiber content of 5 to 15 percent, and a rubbed fiber content of less than 5. The structure is weak medium or coarse subangular blocky.
The bottom tier, where present, has fiber content similar to the subsurface tier. The structure is dominantly massive.
The C horizon, when present, has hue of 2.5Y, value of 6, and chroma of 2 to 6. It is sand or coarse sand.
COMPETING SERIES: This is the Chippeny series, and the closely related Skandia series. The Chippeny soils reaction in the organic horizons range from slightly acid to slightly alkaline. Skandia soils are dysic, with a reaction in the control section is extremely acid.
GEOGRAPHIC SETTING: Trout Bay soils are on seepy side slopes of sandstone benches that are within 3 miles of the Lake Superior shoreline and are moderately deep to bedrock. Slope ranges from 0 to 25 percent. The mean annual precipitation is about 860 millimeters and the mean annual air temperature is about 5 degrees C.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Au Train, Deerton, Gongeau, Jeske, Munising, Shingleton, and Yalmer soils. The somewhat excessively drained Shingleton, well drained Deerton, somewhat poorly drained Jeske and the poorly drained Gongeau soils form a drainage catena with the Trout Bay soils. The moderately well drained Munising and Yalmer soils are on adjacent ground moraines and are very deep to bedrock.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Very poorly drained. Surface runoff is low. Saturated hydraulic conductivity is moderately high to high in the organic tiers, moderately high in the Cr horizon and very low in the bedrock. The depth to the perched wet soil moisture status is from the surface to 30 centimeters below the surface during the period from January to December.
USE AND VEGETATION: These soils are primarily in woodland. Dominant species are sugar maple and red maple with minor amounts of eastern hemlock, eastern white pine, yellow birch, and red maple. Common ground vegetation includes oak fern, jewelweed, sedges, gooseberry, and spinulose wood fern.
DISTRIBUTION AND EXTENT: Central upper peninsula of Michigan. Major Land Resource Areas 93B and 94B. The series is of minor extent.
