LOCATION HUNTING UTEstablished Series
TAXONOMIC CLASS: Fine-silty, mixed, active, calcareous, mesic Aquic Torrifluvents
TYPICAL PEDON: Hunting loam--cultivated. (Colors are for air-dry soil unless otherwise noted.)
Ap--0 to 9 inches; light brownish gray (2.5Y 6/2) loam, dark grayish brown (2.5Y 4/2) moist; weak medium subangular blocky structure; hard, firm, slightly sticky and slightly plastic; few large and fine roots; few medium and fine pores; strongly calcareous; moderately alkaline (pH 8.0); gradual smooth boundary. (6 to 9 inches thick)
C1--9 to 27 inches; light brownish gray (2.5Y 6/2) loam, dark grayish brown (2.5Y 4/2) moist; weak subangular blocky structure; hard, friable, slightly sticky and slightly plastic; few fine roots; few medium and fine pores; strongly effervescent; moderately alkaline (pH 8.0); clear smooth boundary. (9 to 20 inches thick)
C2--27 to 30 inches; light brownish gray (2.5Y 6/2) silt loam, dark grayish brown (2.5Y 4/2) moist; massive; hard, firm, slightly sticky and slightly plastic; few fine roots; few fine pores; strongly effervescent; moderately alkaline (pH 7.9); gradual smooth boundary. (0 to 5 inches thick)
C3--30 to 60 inches; grayish brown (2.5Y 5/2) loam, dark grayish brown (2.5Y 4/2) moist; with few medium distinct dark yellowish brown (10YR 4/5) redoximorphic concentrations; massive; slightly hard, friable; very few fine roots; few fine pores; strongly effervescent; moderately alkaline (pH 8.2).
TYPE LOCATION: Emery County, Utah; 950 feet west and 300 feet south of the NE corner of sec. 19, T. 19 S., R. 8 E. 2-1/2 miles northeast of Clawson.
RANGE IN CHARACTERISTICS: Soil temperatures are 49 to 54 degrees F. Hunting soils have distinct mottles at some depth between 20 and 40 inches, and have water tables between 20 and 40 inches in some seasons.
It ranges from very slightly saline to moderately saline. Carbonate content ranges from 10 to 25 percent. Gypsum veining occur in the lower C horizons below a depth of 12 inches. Texture of the particle-size control section is silt loam, very fine sandy loam, clay loam, or loam and averages 18 to 27 percent clay and less than 15 percent sand coarser than very fine sand.
The A and C horizons have hue of 2.5Y or 5Y, with dry color values of 5 or 6, moist values of 4 or 5, and chroma of 2.
COMPETING SERIES: This is the Memmott (T UT) series. Memmott soils average 27 to 35 percent clay in the particle size control section.
GEOGRAPHIC SETTING: These soils are on alluvial fans and stream terraces on narrow valley floors. They are developed in alluvium from marine shale and sandstone. The climate is arid, with mean annual temperatures of 47 to 52 degrees F. Mean annual precipitation ranges from 6 to 10 inches. Freeze-free period is from 110 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ravola, Billings, Rafael, and Ferron soils. Ravola soils lack mottles. Billings soils have clay loam or silty clay loam particle-size control sections. Ferron and Rafael soils are mottled above 20 inches.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; medium to slow runoff; moderate permeability.
USE AND VEGETATION: Cultivated irrigated areas produce alfalfa, grain and pasture. Potential vegetation is alkali sacaton, Indian ricegrass, and galleta grass.
DISTRIBUTION AND EXTENT: Eastern Utah and western Colorado. This series is moderately extensive. MLRA 34.
MLRA OFFICE RESPONSIBLE: Lakewood, Colorado
SERIES ESTABLISHED: Carbon County, Utah, 1982.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric Epipedon - the layer from surface to 9 inches (Ap horizons)
The classification was changed from Aquic Udifluvent to Aquic Torrifluvents in 9/94. The placement is tentative because the profile lacks redox depletions of chroma 2 or less above 100 centimeters. However, there are redoxiomorphic concentrations and the inference that aquic conditions exist above 100 centimeters. Additional field work is needed.
