LOCATION LITTLE POLE UT+OREstablished Series
TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, frigid Lithic Haploxerolls
TYPICAL PEDON: Little Pole very cobbly sandy clay loam, rangeland. (Colors are for dry soil unless otherwise noted.)
Al--0 to 5 inches; very dark grayish brown (10YR 3/2) very cobbly sandy clay loam, very dark brown (10YR 2/2) moist; weak fine granular structure; slightly hard, friable, slightly sticky and slightly plastic; many fine roots; 50 percent cobbles and gravel; neutral (pH 6.7); clear wavy boundary. (3 to 5 inches thick)
A3--5 to 10 inches; dark grayish brown (10YR 4/2) cobbly sandy clay loam, very dark grayish brown (10YR 3/2) moist; weak coarse and weak fine subangular blocky structure; hard, friable, sticky and plastic; many fine and medium roots; few medium pores; 40 percent cobbles; few thin clay films; neutral (pH 6.7); clear wavy boundary. (3 to 5 inches thick)
B2--10 to 16 inches; grayish brown (10YR 5/2) cobbly sandy clay loam, very dark grayish brown (10YR 3/2) moist, weak coarse and weak fine subangular blocky structure; very hard, firm, sticky and plastic few fine roots; few fine pores; few thin clay films; 50 percent cobbles; neutral (pH 6.8); abrupt irregular boundary. (4 to 10 inches thick)
R--16 to 20 inches; weathered andesite with B2 material like above in fractures
TYPE LOCATION: Wasatch County, Utah, 1.7 miles north of the center of Heber on U. S. Highway 40 and 14 miles east on side road, north of drainage; 1,690 feet south and 1,020 feet east of NW corner of section 21, T.3S., R.SE.
RANGE IN CHARACTERISTICS: Depth to bedrock is 10 to 20 inches. The mean annual soil temperature is about 45 degrees F. and the mean summer soil temperature is about 63 degrees F. The soil is usually moist but is dry for more than 60 consecutive days in all parts of the 7 to 20 inch depth. Base saturation is more than 80 percent.
The A horizon has value of 3 or 4 dry and 2 or 3 moist.
The B2 horizon has value of 5 or 6 dry, 3 or 4 moist and chroma of 2 or 3. Organic matter content is less than 1 percent. This horizon is cobbly sandy clay loam or cobbly loam and has 35 to 50 percent rock fragments. Structure is weak fine to coarse subangular blocky.
COMPETING SERIES: These are the Agassiz, Anatone, Brad, Cedaran, Foxol, Swanner, Van Wagoner and Wallsburg series. Agassiz soils lack cambic horizons and overlie limestone. Anatone and Foxol soils have hue of 7.5YR or redder. Brad soils have very cobbly loamy sand control sections. Cedaran soils have gravelly clay loam B2 horizon, overlie tuff, and have only 12 to 16 inches precipitation. Swanner soils lack cambic horizons and have layers of carbonate accumulation. Van Wagoner soils have very cobbly sandy loam control sections. Wallsburg soils have very cobbly clay argillic horizons.
GEOGRAPHIC SETTING: Little Pole soils occur on mountain slopes with 5 to 60 percent gradients. They formed in residuum derived from intermediate igneous rocks. Elevations range from 6,300 to 8,000 feet. The climate is moist subhumid with mean annual temperature about 43 degrees F., mean summer temperature is about 63 degrees F. and the average annual precipitation is 18 to 25 inches, falling mostly as snow.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Broadhead and Horrocks soils. Broadhead and Horrocks soils are more than 20 inches deep to bedrock and have argillic horizons.
DRAINAGE AND PERMEABILITY: Well drained medium runoff moderate permeability.
USE AND VEGETATION: These soils are used for watershed and spring and fall rangeland for livestock and wildlife. The present vegetation is oakbrush, big sagebrush, birchleaf and curlleaf mountain-mahogany, bitterbrush, snowberry, native bluegrass and needlegrass.
DISTRIBUTION AND EXTENT: Mountain areas of northern Utah. This series is moderately extensive.
