KINGMINE SERIES

The Kingmine series consists of very deep, well drained soils that formed in colluvium and slope alluvium weathered primarily from sandstone and shale. Kingmine soils are on mountain slopes. Slopes range from 30 to 70 percent. The mean annual precipitation is about 72 cm, and the mean annual temperature is about 2.8 degrees C.

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive Mollic Haplocryalfs

COMPETING SERIES: These are the Dromedary and Washboard series. Neither series has accumulations of secondary carbonates. In addition, Washboard soils are derived from andesite, rhyolite, breccia, or tuff.

Mean annual precipitation: 56 to 89 cm
Precipitation pattern: peak periods from July to October and has even distribution throughout the remainder of the year.
Frost-free period: 40 to 70 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Aagard, Millerlake, Tosca, and Datino series. The Aagard and Millerlake soils are on 3 to 30 percent slopes and have mollic epipedons. Datino and Tosca soils are on north facing slopes at lower elevations; they do not have an argillic horizon and have a typic ustic soil moisture regime.

DRAINAGE AND PERMEABILITY: Well drained, very high runoff, moderately slow permeability.

USE AND VEGETATION: Grazing, mining, and timberland. Vegetation consists of aspen, Douglas fir, Oregon grape, gooseberry, snowberry, wild rose, nodding brome, mountain brome, letterman needlegrass, Colombia needlegrass, and bluegrass.

DISTRIBUTION AND EXTENT: Central Utah mountains; LRR E, MLRA 48A; these soils are of small extent; about 910 hectares (2,250 acres) in Carbon, Emery and Utah Counties, Utah.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana

SERIES ESTABLISHED: Utah County, Utah, Duchesne soil survey area, 2011. The soil is named for the nearby King Mine.

REMARKS:
Diagnostic horizons and features recognized in this pedon are:
Series control section: The zone from 0 to 165 cm.
Particle-size control section: The zone from 25 to 79 cm. (Bt horizons)
Ochric epipedon: The zone from 0 to 25 cm (A and AE horizons)
Argillic horizon: The zone from 25 to 79 cm (Bt horizons)
Calcic horizon: The zone from 112 to 142 cm. (Bk2 horizon)

Remarks: A continuous O horizon from 5 to 8 cm thick is present on some pedons. A Btk horizon and/or a BCk horizon is present in some pedons. The color requirements for the mollic intergrade are met by mixing the top 18 cm of the soil.

The assignment of the cation-exchange activity class is inferred from lab data from similar soils in the surrounding area.
