Ck--42 to 56 inches; pale brown (10YR 6/3) gravelly sandy loam, yellowish brown (10YR 5/4) moist; single grained; slightly hard, friable, nonsticky and nonplastic; some lime coating on the pebbles; neutral (pH 7.3).
TYPE LOCATION: Utah County, Utah; 2 miles north of Lehi; 2,400 feet west and 1,200 feet north of the SE corner of section 29, T.4S., R.1E.
RANGE IN CHARACTERISTICS: The soil is usually moist, but is dry in the 7 to 20 inch depth for 60 days or more. The mean annual soil temperature at 20 inches is 49 to 54 degrees F. The average summer temperature is 65 to 75 degrees F.
The solum is 30 to 45 inches thick. The soil is gravelly throughout, and may overlie strongly calcareous lake sediments at depths of 30 inches or more. The 10 to 40 inch control section has less than 25 percent coarse and very coarse sand and more than 15 percent fine and very fine sand.
The A horizon has hue of 10YR or 7.5YR, value of 4 or 5 dry, 2 or 3 moist, and chroma of 2 and 3. It is gravelly sandy loam or loam with less than 18 percent clay and may contain some cobble and stone. This horizon has weak to moderate medium subangular blocky structure.
The weak Ck horizon, if present, is thin lime coating on underside of coarse fragments. The C horizon has hue of 7.5YR or 10YR, value of 5 through 7 dry, 4 or 5 moist, and chroma of 2 or 3.
COMPETING SERIES: These are the Anders, Chenoweth, Juliaetta, Kilburn, Knutsen, Laidlaw, Phoebe, Pleasant View, Redd, Sheridan, and Uhlig series. Anders soils have a lithic contact at depths of 20 to 40 inches. Chenoweth soils are nongravelly except for few lenses in some pedons. Juliaetta, Phoebe, Sheridan, and Uhlig soils have less than 15 percent coarse fragments in the series control section. Kilburn soils have more than 35 percent coarse fragments in the 10 to 40 inch control section. Knutsen soils have more than 25 percent coarse and very coarse sand and less than 15 percent fine and very fine sand in the soil fraction of the control section. Laidlaw soils contain a high content of pumice. Pleasant View soils have calcic horizons and have mollic epipedons more than 20 inches thick. Ridd soils have argillic horizons.
GEOGRAPHIC SETTING: The Cleverly soils are on gently sloping to very steep alluvial fans and colluvial slopes, at elevations of 4,600 to 5,600 feet. Slope gradients are 3 to 60 percent. The soils formed in medium textured alluvium, dominantly from finely fractured quartzite rocks. The climate is dry subhumid with an average annual precipitation of 14 to 20 inches. The mean annual temperature is 46 to 59 degrees F., and the mean summer temperature is 65 to 75 degrees F. The frost free season is 150 to 190 days, although shorter seasons would not be excluded.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Kilburn soils.
DRAINAGE AND PERMEABILITY: Well drained; slow runoff; rapid permeability.
USE AND VEGETATION: These soils are used for range and nonirrigated small grain cropland. Present vegetation is dominantly cheatgrass, oakbrush, and weeds.
DISTRIBUTION AND EXTENT: The soils are on the Wasatch front in the Great Basin and are inextensive.
