corner of sec. 11, T.27S., R.8W.
RANGE IN CHARACTERISTICS: The solum is 20 to 30 inches thick. Depth to the indurated lime hardpan ranges from 30 to 40 inches. The organic matter content of 1 percent or more extends to less than 20 inches. The mean annual soil temperature is 42 to 46 degrees F., and the mean summer soil temperature at a depth of 20 inches is 60 to 63 degrees F. These soils are moist in some part of the moisture control section more than 50 percent of time the soil temperature is above 41 degrees F. but are continually dry for 50 to 70 consecutive days during the summer months in more than 6 out of 10 years.
The Al horizon has chroma of 2 or 3. It has fine granular or subangular blocky structure. This horizon is soft or slightly hard. It is 5 to 10 inches thick.
The B2t horizon has value of 4 or 5 dry, 2 or 3 moist, and chroma of 2 or 3. It is clay loam containing 27 to 35 percent clay. This horizon has weak coarse or moderate fine angular blocky structure.
The B3tca horizon has loam than 1 percent organic matter. The Cca horizon hds value of 7 or 8 dry.
COMPETING SERIES: These are the Black Ridge and May Day series. Black Ridge soils have more than 35 percent clay in the argillic horizon and have a mean annual temperature of more than 47 degrees F. May Day soils have rock fragments throughout the profile and are less than 20 inches deep over the indurated hardpan
GEOGRAPHIC SETTING: Paice soils are on rolling hills at elevations of 6,900 to 7,400 feet. Slopes range from 3 to 10 percent. The soils formed in about 30 inches of soil material derived from basalt. The climate is moist subhumid. Mean annual temperature is 40 to 44 degrees F., mean summer temperature is 61 to 64 degrees F., and the average annual precipitation is 14 to 18 inches. Frost-free period is 80 to 100 days.
PRINCIPAL ASSOCIATED SOILS: These are the competing Black Ridge soils.
DRAINAGE AND PERMEABILITY: Well-drained; medium runoff; moderate permeability to hardpan.
USE AND VEGETATION: Used for summer range for cattle, spring range for sheep, and winter range for big game. Present vegetation is mostly big sagebrush and Gambel oak.
DISTRIBUTION AND EXTENT: Southwestern Utah. Maple Mountain area in East Beaver Area. This series is inextensive.
