TYPE LOCATION: Wasatch County, Utah; about 15 miles northwest of Heber at a point 1 mile west of Park City and Cloud Rim Road Junction at the head of Pine Creek; 1,200 feet south and 4,360 feet west of the NE corner of section 31, T.2S., R.4E.
RANGE IN CHARACTERISTICS: Solum thickness is more than 40 inches. Cobbles and stones range from 20 to 35 percent throughout the profile. The mean annual soil temperature is about 40 degrees F. and the mean annual summer soil temperature is about 54 degrees F. Base saturation is less than 60 percent in some part above a depth of 30 inches. The soils are usually moist and are not dry for as much as 90 cumulative days in some subhorizon. A thin layer of needles and tuff occur in places mainly under the tree canopy.
The Al horizon has value of 4 or 5 dry, 2 through 4 moist, and chroma of 2 or 3. The moist value of 2 or 3 extends to depths of 2 inches or less.
The B2 horizon has value of 5 or 6 dry, 4 or 5 moist and chroma of 3 through 5. It is cobbly sandy loam or cobbly coarse sandy loam. Clay films are thin and patchy, occurring mostly in pores and are more evident deep in the profile.
COMPETING SERIES: These soils are the Cuberant, Leal, Marsell and Scout series. Cuberant and Scout soils have more than 35 percent rock fragments in the control section and have base saturation of more than 60 percent. Cuberant soils are 20 to 40 inches deep over bedrock. Leal soils have B2ir horizons, and A2 horizons. Marsell soils have more than 35 percent rock fragments in the control section.
GEOGRAPHIC SETTING: Lake Janee soils occur on moderately steep to very steep ground and lateral moraines derived from coarse grained intermediate igneous parent rocks. Slopes are 15 to 40 percent. Elevation ranges from 8,000 to 10,000 feet above sea level. The climate is humid, with an average annual precipitation of 25 to 35 inches that falls mostly as snow. The mean annual temperature is about 42 degrees F., mean summer temperature is about 54 degrees F. and the frost-free period is 50 to 80 days. Lake Janee Series
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Hailman and Buell soils. Hailman soils have thick mollic epipedons. Buell soils have thick dark colored umbric epipedons and have control sections containing more than 35 percent pebbles and cobbles.
DISTRIBUTION AND EXTENT: Well drained; medium runoff; moderate to moderately rapid permeability.
USE AND VEGETATION: These soils are used for watershed, wildlife habitat, limited timber production and limited summer grazing by livestock. Native plants are subalpine fir and Englemann spruce with scattered aspen. Understory is gooseberry, elderberry, elkweed and sedges.
DISTRIBUTION AND EXTENT: High mountain areas in north-central Utah. This series is inextensive.
