LOCATION SLIMLAKE WIEstablished Series
TAXONOMIC CLASS: Sandy, mixed, frigid Oxyaquic Dystrudepts
TYPICAL PEDON: Slimlake sandy loam, on a west-facing, plane slope of 1 percent, in a forested area, at an elevation of about 1,170 feet. (Colors are for moist soil unless otherwise stated.
A--0 to 6 inches; very dark brown (10YR 2/2) sandy loam, dark gray (10YR 4/1) dry; moderate medium granular structure; friable; many very fine to coarse roots; many fine and medium tubular pores; strongly acid; clear smooth boundary. (0 to 8 inches thick)
Bw1--6 to 12 inches; dark yellowish brown (10YR 4/4) sandy loam; moderate very fine subangular blocky structure; friable; common fine to coarse roots; common fine and medium tubular pores; 5 percent gravel; slightly acid; clear wavy boundary.
Bw2--12 to 17 inches; dark yellowish brown (10YR 4/4) sandy loam; moderate medium subangular blocky structure; friable; common fine to coarse roots; common fine tubular and vesicular pores; 5 percent gravel; slightly acid; clear wavy boundary. (Combined thickness of the Bw horizon ranges from 7 to 40 inches.)
2BC1--17 to 23 inches; strong brown (7.5YR 5/6) gravelly sand; weak coarse subangular block structure in place, single grain where disturbed; loose; few fine to coarse roots; 28 percent gravel and 5 percent cobbles; slightly acid; gradual wavy boundary.
2BC2--23 to 42 inches; strong brown (7.5YR 5/6) gravelly sand; weak coarse subangular blocky structure in place, single grain where disturbed; very friable; few fine to coarse roots; few fine distinct strong brown (7.5YR 5/8) masses of iron accumulation; 20 percent gravel and 5 percent cobbles; slightly acid; gradual wavy boundary.
2C1--42 to 53 inches; brown (7.5YR 4/4) gravelly sand; single grain; loose; few fine to medium roots; 18 percent gravel; common medium prominent strong brown (7.5YR 5/8) masses of iron accumulation; 1/8 to 1/2 inch strata of dark reddish brown (5YR 3/4) loamy sand (total thickness is 1 inch); moderate medium subangular blocky structure; very friable; slightly acid; gradual wavy boundary.
2C2--53 to 80 inches; brown (7.5YR 4/4) sand; single grain; loose; 10 percent gravel; few medium prominent strong brown (7.5YR 5/8) masses of iron accumulation; 1/8 to 1/2 inch strata of brown (7.5YR 4/4) loamy sand (total thickness is 5 inches); weak fine subangular blocky structure; very friable; slightly acid.
TYPE LOCATION: Washburn County, Wisconsin; about 5 miles west of Stone Lake; located about 1,500 feet south and 100 feet west of the northeast corner of section 19, T. 39 N., R. 10 W.; USGS Potato Lake topographic quadrangle; lat. 45 degrees 51 minutes 8 seconds N. and long. 91 degrees 38 minutes 39 seconds W., NAD 83.
RANGE IN CHARACTERISTICS: Thickness of the loamy mantle and depth to stratified sandy outwash ranges from 10 to 24 inches. Volume of gravel ranges from 0 to 10 percent in the loamy mantle. Volume of gravel ranges from 10 to 25 percent in the sandy outwash as a weighted average, but ranges from 0 to 40 percent in individual strata. Volume of cobbles ranges from 0 to 5 percent throughout. Reaction ranges from strongly acid to slightly acid throughout the profile.
The A horizon has value of 2 or 3 and chroma of 1 or 2. Texture is sandy loam.
The Bw horizon has value of 4 or 5 and chroma of 4 to 6. Texture is sandy loam.
The 2BC horizon has hue of 7.5YR, value of 4 or 5 and chroma of 4 to 6. Texture is loamy sand or sand and the gravelly analogs.
The 2C horizon has hue of 5YR or 7.5YR, value of 3 to 5 and chroma of 4 to 6. Texture is sand, coarse sand or the gravelly or very gravelly analogs and typically includes thin strata of loamy sand. Total sand content is over 90 percent.
COMPETING SERIES: This is the Spoonerhill series. A similar soil is the Manitowish series. Spoonerhill soils formed in till, do not have stratification and have less than 90 percent sand in the lower part of the series control section. Manitowish soils have a spodic horizon.
GEOGRAPHIC SETTING: These soils are on outwash plains, stream terraces, and moraines. Slope ranges from 0 to 3 percent. They formed in 10 to 24 inches of loamy alluvium and the underlying sandy outwash. Mean annual air temperature ranges from 39 to 43 degrees F. Mean annual precipitation ranges from 27 to 31 inches. The frost-free period ranges from about 100 to 130 days. Elevation ranges from 1,000 to 1,300 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cress, Wurtsmith, and Spoonerhill(T) soils. The somewhat excessively drained Cress soils are on slightly higher landscape positions. The moderately well drained Wurtsmith soils are on adjacent areas where the loamy mantle is absent. The moderately well drained Spoonerhill(T) soils are on nearby landscapes where the Spoonerhill(T) soils formed in sandy glacial till.
DRAINAGE AND PERMEABILITY: Moderately well drained. Surface runoff is slow. Permeability is moderate or moderately rapid in the loamy mantle and rapid or very rapid in the sandy outwash. Slimlake soils have a seasonal high water table at depths of 2.5 to 3.5 feet for 1 month or more per year at some time during the period of September to June in normal years.
USE AND VEGETATION: Most areas of this soil are used for woodland. Native vegetation is mixed deciduous-coniferous forest. Common trees are Quaking Aspen, Red Maple, and Red Pine.
DISTRIBUTION AND EXTENT: Northwestern Wisconsin. This soil is of small extent.
