COMPETING SERIES: These are the Canyonfork, Cavehill, Fontreen, Granzan, Highup, Lizdale, Lizzant, Lonjon, and Sylvaniam series.
Cavehill soils have 30 to 50 cm thick mollic epipedons.
Canyonfork,
Fontreen
Lizdale, and
Lizzant soils are very deep.
Granzan soils are 100 to 150 cm deep to bedrock.
Highup soils have 12 to 18 percent clay in the particle-size control section.
Lonjon soils are typically neutral in the A horizon and have Bw horizons.
Sylvaniam soils have mollic epipedons 30 to 43 cm thick.
GEOGRAPHIC SETTING: Cedarcabin soils are on fan remnants, occurring on north slopes at lower elevations and all aspects at higher elevations.
These soils formed in residuum and colluvium derived from fanglomerate, consisting of limestone, dolomite, and minor amounts of quartzite.
Slopes are 15 to 50 percent.
Elevations range from 1,950 to 2,560 meters.
The climate is dry-subhumid with cool, moist winters and warm, dry summers.
The mean annual precipitation is 400 to 500 mm.
The mean annual temperature is 4 to 6 degrees C.
The frost-free period is 40 to 70 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Bigwash, competing
Canyonfork, and
Noski soils.
Bigwash, and Canyonfork soils are very deep.
Noski soils are shallow to indurated fanglomerate.
DRAINAGE AND PERMEABILITY: Well drained; medium to high surface runoff; moderately slow permeability; moderately high saturated hydraulic conductivity.
USE AND VEGETATION: Cedarcabin soils are used for recreation, livestock grazing, and wildlife habitat. The potential native vegetation is mainly an overstory of singleleaf pinyon and Utah juniper, with an understory of bluebunch wheatgrass, Indian ricegrass, and black sagebrush. This pedon is correlated to Ecological Site R028AY0074NV, Singleleaf pinyon-Utah juniper/black sagebrush/bluebunch wheatgrass.
DISTRIBUTION AND EXTENT: Eastern Nevada. These soils are not extensive. MLRA 28A.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Phoenix, Arizona.
