TYPE LOCATION: Box Elder, County, Utah; about 2 miles south of Tremonton, 1 mile south and 1/2 mile east of the Third Ward Church; 900 feet north and 1,800 feet west of the southeast corner of sec. 22, T.11N., R.3W., SLBM.
RANGE IN CHARACTERISTICS: The mean annual soil temperature is about 50 degrees F. and the mean summer soil temperature is about 72 degrees F. The soils are usually moist; they are moist in some part of the moisture control section for more than one-half of the time the soil temperature is above 5 degrees C. (41 degrees F.). The soils are dry in all parts of the moisture control section for 60 to 90 consecutive days during the summer months.
The mollic epipedon is 10 to 20 inches thick and the solum is 19 to 36 inches thick. The control section is silty clay loam, averaging about 35 to 40 percent clay. These soils have a fluctuating water table at depths of 40 to more than 60 inches.
The A horizon has chroma of 2 or 3. It is slightly to strongly alkaline and slightly to moderately calcareous.
The B horizon has hue of 10YR or 7.5YR, value of 5 or 6 dry, 3 or 4 moist and chroma of 2 through 4. It is silty clay loam or silty clay. It is slightly to strongly alkaline and moderately to strongly calcareous.
The Ck horizon has hue of 7.5YR or 10YR, value of 6 through 8 dry, 4 through 6 moist, and chroma of 2 through 4 dry and 3 or 4 moist. It has fine, faint to prominent mottles at depths of 30 inches or more. It is silty clay to silty clay loam. It is strongly to very strongly alkaline.
COMPETING SERIES: These are the Collett, Fielding, Fingal, Fridlo, Nibley and Parleys series. Collett soils have mottles with chroma of 2 or less above 30 inches. Fielding soils have 20 to 24 percent clay in the control section. Fingal soils have mottles with chroma of 2 within 30 inches or are saturated for more than 90 days within 40 inches. Fridlo soils have natric horizons with 24 to 32 percent clay. Nibley soils have argillic horizons and have mottles with chroma of 2 within 30 inches or have water table within 40 inches for 90 days or more when undrained. Parleys soils have noncalcareous A and B horizons and argillic horizon with less than 35 percent clay.
GEOGRAPHIC SETTING: These soils are on nearly level lake terraces and plains at elevations of 4,200 to 4,355 feet. The parent materials are fine and moderately fine textured lacustrine deposits. The climate is dry subhumid with a mean annual temperature of 48 degrees F., and a mean summer temperature of 70 degrees F. The frost-free period is about 140 days. The average annual precipitation is 14 to 16 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Collett, Fielding, Fridlo and Parleys soils and the Kidman, Magna and Timpanogos soils. Kidman soils have less than 18 percent clay and more than 15 percent coarser than very fine sand in the control section and are noncalcareous in the A and B horizons. Magna soils have calcic horizons with hues of 2.5Y or 5Y immediately below the mollic epipedon and have more than 40 percent carbonate equivalent in the control sections. Timpanogos soils have argillic horizons.
DRAINAGE AND PERMEABILITY: Moderately well drained; slow runoff; slow permeability.
USE AND VEGETATION: Used for irrigated cropland.
DISTRIBUTION AND EXTENT: Northern Utah. These soils are inextensive.
