GOGOMAIN SERIES

The Gogomain series consists of very deep, poorly drained soils formed in sandy and loamy glaciofluvial deposits and in the underlying clayey calcareous glaciolacustrine deposits on lake plains. Permeability is moderate in the upper part of the soil and very slow in the lower part. Slopes range from 0 to 2 percent. Mean annual precipitation is about 30 inches, and mean annual temperature is about 43 degrees F.

TAXONOMIC CLASS: Coarse-loamy over clayey, mixed, active, nonacid, frigid Aeric Epiaquepts

TYPICAL PEDON: Gogomain very fine sandy loam - on a 1 percent slope in a forested area. (Colors are for moist soil unless otherwise stated.)

A--0 to 6 inches; black (10YR 2/1) very fine sandy loam, dark gray (10YR 4/1) dry; moderate medium granular structure; very friable; many fine to coarse roots; common fine pores; moderately acid; abrupt smooth boundary. (4 to 6 inches thick)

Eg--6 to 10 inches; grayish brown (10YR 5/2) very fine sandy loam; weak medium platy structure parting to weak very fine subangular blocky; very friable; common fine and medium roots; common fine pores; few medium distinct yellowish brown (10YR 5/6) iron accumulations throughout; neutral; abrupt smooth boundary. (1 to 5 inches thick)

Bw1--10 to 19 inches; pale brown (10YR 6/3) loamy very fine sand; weak medium platy structure parting to weak very fine subangular blocky; very friable; common fine roots; few medium distinct dark gray (10YR 4/1) iron depletions and common medium distinct yellowish brown (10YR 5/6) iron accumulations throughout; slightly alkaline; clear wavy boundary.

Bw2--19 to 29 inches; brown (10YR 5/3) very fine sand; moderate medium and thick platy structure parting to weak very fine subangular blocky; very friable; few very fine and fine roots; few medium distinct dark gray (10YR 4/1) iron depletions and common medium distinct yellowish brown (10YR 5/6) iron accumulations throughout; moderately alkaline; clear wavy boundary. (Combined thickness of Bw horizon is 7 to 27 inches.)

Bg--29 to 37 inches; brown (7.5YR 5/2) very fine sand; moderate medium subangular blocky structure; very friable; few very fine roots; moderately alkaline; abrupt smooth boundary. (0 to 8 inches thick)

2C--37 to 39 inches; light reddish brown (5YR 6/3) clay; weak medium and thick platy structure parting to weak very fine subangular blocky; firm; few very fine roots; common coarse distinct yellowish red (5YR 5/6) iron accumulations and gray (5YR 5/1) iron depletions throughout; slightly effervescent; moderately alkaline; abrupt smooth boundary.

2Cg--39 to 60 inches; pinkish gray (5YR 6/2) clay; weak medium and thick platy structure parting to weak fine subangular blocky; firm; few very fine roots; few coarse distinct yellowish red (5YR 5/6) iron accumulations and few coarse faint gray (5YR 5/1) iron depletions throughout; strongly effervescent; moderately alkaline.

TYPE LOCATION: Chippewa County, Michigan; about 1 mile west of Rudyard; 1,100 feet north and 135 feet west of the southeast corner, sec. 1, T. 44 N., R. 3 W.

RANGE IN CHARACTERISTICS: Solum depth and depth to free carbonates ranges from 18 to 40 inches.

Some pedons have thin organic surface layers (Oa horizons) 1 to 6 inches thick with colors similar to the A horizon.

The A horizon has hue of 10YR or 7.5YR, value of 2 or 3, and chroma of 1 or 2. It is very fine sandy loam, loamy very fine sand, very fine sand, or silt loam. Some pedons have an Ap horizon up to 10 inches thick with similar colors. Reaction of the A, Ap or Oa horizon ranges from moderately acid to neutral.

The Eg horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 1 or 2. It has textures and reaction similar to the A or Ap.

The Bw horizons have hues of 7.5YR or 10YR, value of 5 or 6, and chroma of 2 to 4. They are very fine sandy loam, loamy very fine sand, very fine sand or silt loam. Reaction ranges from neutral to moderately alkaline.

The Bg horizon has hue of 7.5YR, 2.5Y, or 10YR; value of 4 to 6; and chroma of 1 or 2. They are very fine sandy loam, loamy very fine sand, very fine sand or silt loam. Reaction ranges from neutral to moderately alkaline.


The 2C horizons have hues of 7.5YR, 5YR, or 2.5YR; value of 4 to 6, and chroma of 2 to 4. They are clay or silty clay. Reaction is slightly or moderately alkaline.

COMPETING SERIES: There are no other series in the family. The closely related Swanton soils are superactive and have illitic mineralogy in the substratum.

GEOGRAPHIC SETTING: The Gogomain soils occupy nearly level to depressional areas and formed in sandy and loamy glaciofluvial deposits and in the underlying clayey calcareous glaciolacustrine deposits on lake plains. Slopes are 0 to 2 percent. Mean annual precipitation is about 28 to 31 inches, and the mean annual air temperature is about 41 to 43 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Biscuit, Fibre, and Pickford soils. The somewhat poorly drained Biscuit soil is in slightly higher landscape positions and is in a drainage sequence with the Gogomain soil. The poorly drained Fibre and Pickford soils are associated soils on similar landscape positions. Fibre soils have a sandy surface and subsoil and the Pickford soils are clayey throughout.

DRAINAGE AND PERMEABILITY: Poorly drained. The representative depth to wet soil moisture status is at the surface to one foot below the surface at times during the months of March, April, May, June, September, October, November, and December. The representative depth of ponding is from 0.2 to 0.5 foot at some time during the period from October to June. Runoff is negligible to low, dependent on slope. Permeability is moderate in the upper loamy part and very slow in the lower clayey part.

USE AND VEGETATION: Most areas of this soil are idle farmland that has grown back to woodland and brush. Common tree species include quaking aspen, balsam fir, northern whitecedar, tamarack, paper birch, balsam poplar and speckled alder.

DISTRIBUTION AND EXTENT: Eastern Upper Peninsula of Michigan. The series is of moderate extent.
