(Combined thickness of the Bt horizons ranges from 8 to 30 inches.)
2Cg-- 22 to 35 inches, gray (5YR 5/1) silt loam (color of plate faces); many fine distinct reddish brown (2.5YR 4/3), common medium distinct pinkish gray (5YR 6/2), and common medium distinct olive yellow (2.5Y 6/6) mottles or color variegations; moderate thin platy inherited structure; hard; few fine and medium roots; few, thin white (10YR 8/1) patches of secondary carbonates; 5 percent rock fragments; strongly effervescent, moderately alkaline; abrupt smooth boundary. (0 to 20 inches thick.)
R-- 35 inches; hard Lockport Dolomite bedrock.
TYPE LOCATION: Located on the Tuscarora Nation, Niagara County, New York, east of Black Nose Spring Road, south of Bond Lake County Park.
RANGE IN CHARACTERISTICS: Solum thickness and depth to bedrock ranges from 20 to 40 inches. Commonly there is a layer influenced by till or residuum over the bedrock. Depth to carbonates range from 20 to 40 inches. Rock fragments range from 0 to 2 percent in the solum and from 0 to 20 percent in the substratum.
The Ap or A horizon has hue of 5YR through 10YR, value of 2 or 3, and chroma of 0 to 2. Texture ranges from silt loam to silty clay. Reaction ranges from moderately acid through slightly alkaline.
The Btg horizons have hue of 2.5YR through 7.5YR, value of 4 through 6 and chroma of 1 or 2. Texture ranges from silty clay loam to clay. Reaction ranges from slightly acid to slightly alkaline
The C horizon, or 2C horizon, where present, have hue of 2.5YR through 7.5YR, value of 3 through 6, and chroma of 1 or 2. Texture ranges from silt loam to clay. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: There are no competing series in this family.
Canandaigua, Lakemont, and Fonda soils are in related families. These soils are greater than 80 inches to bedrock.
GEOGRAPHIC SETTING: Uwihreh soils formed from glacial lake sediments in slight depressions on the dipslopes of paleozoic age cuestas or on bedrock controlled glacial age lake beds. Slope ranges from 0 to 3 percent. Mean annual air temperature ranges from 46 degrees to 50 degrees F., mean annual precipitation ranges from 30 to 40 inches, and the mean frost-free period ranges from 140 to 170 days. Elevation ranges from 300 to 800 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Lockport, Lakemont, Odessa, Churchville, and Yunenyeti soils. The Churchville, Odessa, and the Lockport soils have a horizon above 30 inches that is dominated by soil colors in which chroma higher than two dominates. Lakemont is greater than 80 inches to bedrock. The Yunenyeti has a fine loamy family texture.
DRAINAGE AND PERMEABILITY: Poorly drained. The potential for surface runoff is low to very high, or is negligible. Permeability is moderate to moderately slow in the surface and slow or very slow subsoil and substratum.
USE AND VEGETATION: Cleared areas are used for growing hay and pasture management. Native vegetation is red maple, elm, white ash, hickory, oak, white cedar, hemlock, and white pine.
DISTRIBUTION AND EXTENT: The Erie and Ontario Lake plains of New York. MLRA 101. This series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Tuscarora Nation, Niagara County, New York, 2005
REMARKS: Uwihreh is from the Tuscarora language and means swamp. It is pronounced oo.weh.reh (os like those in ooze, the es are pronounced like the e in wet, hs are silent).
Actual Lat/Long of profile not printed on the OSD by agreement with the Tuscarora Nation.
Diagnostic horizons and features recognized in this pedon are:
1) Mollic subgroup-meets the requirements for the mollic epipedon except thickness, after mixing the upper 18 cm. Zone from 0 to 6 inches (A horizon) and 1 inch of the B/E horizon.
2) Argillic Horizon---the zone from 12 to 22 inches.
3) Endoaqualfs great group---redoximorphic features in all layers between 25 and 40 cm, and 50 percent redox depletions with chroma of 2 or less on the faces of peds and redox concentrations in the top 12.5 cm of the argillic horizon. Endosaturation, and does not meet any of the stipulative criteria of any of the other great groups of Aqualfs.
