TYPE LOCATION: Hubbard County, Minnesota; about 5 miles northeast of Dorset; 800 feet north and 1300 feet west of the southeast corner of sec. 18, T.141N., R.33W.; USGS Mantrap Lake quadrangle; lat. 47 degrees 1 minute 26.2 seconds N. and long. 94 degrees 54 minutes 6.3 seconds W., NAD27.
RANGE IN CHARACTERISTICS: Depth to free carbonates ranges from 30 to more than 60 inches. Gravel content ranges from 2 to 10 percent throughout. Cobble, stone, and boulder content ranges up to 35 percent in some pedons.
The A horizon has hue of 10YR, value of 2 to 4 and chroma of 1 or 2. It is sandy loam, fine sandy loam, or loam. It is moderately acid or slightly acid.
The E horizon has hue of 10YR, value of 4 to 7 and chroma of 3 or 4. It is loamy sand, loamy fine sand, sandy loam, or fine sandy loam. It is moderately acid or slightly acid.
All pedons have E/B, B/E, EB, or BE horizons with colors and textures similar to the E and Bt horizons.
The Bt horizon has hue of 10YR or 7.5YR, value of 4 or 5 and chroma of 4 or 5. It is sandy loam, fine sandy loam, or loam. It ranges from 10 to 18 percent clay. It is moderately acid to neutral.
The C horizon has hue of 2.5Y or 10YR, value of 4 to 6 and chroma 3 to 5. It is sandy loam, fine sandy loam, loamy sand, or loamy fine sand with less than 18 percent clay. It is slightly alkaline or moderately alkaline.
COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Steamboat soils have plane to convex slopes with gradients of 1 to 65 percent. They are on moraines. They formed in loamy glacial till of Wisconsinan Age. Mean annual air temperature ranges from 37 to 45 degrees F. Mean annual precipitation ranges from 24 to 33 inches. Frost-free days range from 90 to 172 days. Elevation above sea level ranges from 670 to 1450 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Eagleview, Potatolake (T), Two Inlets, and organic soils. The moderately well drained Potatolake soils are on nearly level to slightly convex positions and have silty materials over sandy stratified materials. The Eagleview and Two Inlets soils are in similar landscape positions and are sandy and gravelly throughout. Organic soils are in depressions.
DRAINAGE AND PERMEABILITY: Well drained. Surface runoff is moderately low to high. Permeability is moderate or moderately slow.
USE AND VEGETATION: Most areas are used as woodland but some areas are used for cropland, hayland or pastureland. Native vegetation is quaking aspen, paper birch, and northern hardwoods.
DISTRIBUTION AND EXTENT: Central and northern Minnesota. This series is not extensive.
