LOCATION PULLUP MIEstablished Series
TAXONOMIC CLASS: Sandy, mixed, frigid, ortstein Typic Durorthods
TYPICAL PEDON: Pullup sand - on an 11 percent slope in a forested area. (Colors are for moist soils unless otherwise stated.)
Oi--2 to 0 inches; slightly decomposed leaf litter. (1 to 3 inches thick)
E--0 to 8 inches; light brownish gray (10YR 6/2) fine sand, light gray (10YR 7/2) dry; weak medium subangular blocky structure; very friable; common fine to coarse roots; strongly acid; abrupt wavy boundary. ( 5 to 15 inches thick)
Bs--8 to 12 inches; dark brown (7.5YR 4/4) fine sand; weak fine subangular blocky structure; very friable; common fine to coarse roots; moderately acid; clear wavy boundary. (3 to 13 inches thick)
Bsm--12 to 22 inches; dark brown (7.5YR 4/4), strong brown (7.5YR 5/8) and pinkish gray (7.5YR 6/2) fine sand; massive; very hard; ortstein occupies 90 percent of the horizon and is strongly cemented; ortstein occurs as a nearly continuous layer with tongues that extend to a depth of 38 inches; few medium and fine roots; moderately acid; clear irregular boundary. (7 to 15 inches thick)
C--22 to 80 inches; very pale brown (10YR 7/4) fine sand; single grain; loose; slightly acid.
TYPE LOCATION: Mackinac County, Michigan; about 1/4 mile north of Cranberry Lake; 2145 feet south of center Sec. 11, T. 44 N., R. 9 W.
RANGE IN CHARACTERISTICS: (Unless otherwise stated the depths in this paragraph are measured from the mineral surface.)The solum is 20 to 40 inches thick. Depth to the ortstein ranges from 10 to 20 inches and ranges from 7 to 15 inches thick.
If an A horizon is present it has a hue of 7.5YR, 10YR, or is neutral, value of 2 to 4, and a chroma of 0 to 2.
The E horizon has a hue of 10YR or 7.5YR, value of 5 to 7, and chroma of 2. The A and E horizons are sand or fine sand. Reaction of the A and E horizons range from very strongly acid to moderately acid.
The Bs horizon has hue of 5YR or 7.5YR, value of 3 or 4, and chroma of 4. It is sand or fine sand. Reaction ranges from very strongly acid to moderately acid.
The Bsm horizon has hue of 7.5YR, value of 4 to 6 and chroma of 2 to 8. Greater than 50 percent of the color has value of 3 or 4 and chroma of 4. It is sand or fine sand. Reaction ranges from very strongly acid to moderately acid.
Some pedons have a BC horizon with hue of 10YR or 7.5YR, value of 5 or 6, and chroma of 4 to 6. It is sand or fine sand. Reaction is moderately acid or slightly acid.
The C horizon has hue of 10YR or 7.5YR, value of 5 to 7, and chroma 4 to 6. It is sand or fine sand. Reaction is moderately acid or slightly acid.
COMPETING SERIES: These are the Paquin and Wallace series in the same family. Paquin soils have redoximorphic features within 30 to 40 inches. Wallace soils have Bhs or Bhsm horizons with and value and chroma of 2 or 3.
GEOGRAPHIC SETTING: Pullup soils are on bars, dunes and beach ridges. Slopes range from 0 to 60 percent. The mean annual precipitation ranges from 28 to 32 inches. The mean annual temperature ranges from 42 to 44 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dawson, Markey, Finch, Paquin, Rubicon, and Wallace soils. The very poorly drained Dawson and Markey soils have organic surface layers more than 16 inches thick. Finch soils are somewhat poorly drained. Paquin soils are moderately well drained. Rubicon soils have less than 50 percent ortstein in the spodic horizon. Wallace soils are well drained.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained. Surface runoff is slow. Permeability is moderate or moderately rapid through the ortstein layers and rapid in the remainder of the profile.
USE AND VEGETATION: Most areas of this soil are forested. Common trees are quaking aspen, red maple, eastern white pine, paper birch, balsam fir, white spruce, and red pine.
DISTRIBUTION AND EXTENT: Eastern and central Upper Peninsula of Michigan. This soil is of minor extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Mackinac County, Michigan, 1994.
REMARKS: Diagnostic horizons and features recognized in this pedon are: ochric and albic horizon - the zone from the 2 to 8 inches (E horizon); spodic horizon - the zone from 8 to 22 inches (Bs and Bsm horizons); ortstein feature - spodic horizon is cemented in 90 percent or more of each pedon.
