Fish Creek Soil Investigation
Bachus Benteen, Cambern Echmoor, Senchert. ~uawval, Vadnais, and Winu soils: have a
lithic contact at depths of 20 to 40 inches.
Bavdark soils: have rock fragments of gneiss and schist
Cro don soils: has a lithic contact at 40 to 60 inches
Decross soils: have a zone of calcium carbonate accumulation at depths of 20 to 40 inches.
Crvstalbutte, Dehana, Demast and Dranyon soils: have 20 to 35 percent rock fragments in the
particle size control section.
Davtone soils: have hue of SYR or l OR in the Bt horizon.
Dranburn soils: have silty clay loam particle size control sections.
Gordo soils: have hue of SYR or 2.5YR in the Bt horizon.
Hagenbarth and Thulenah soils are dry for more than 90 cumulative days from July to October
(xeric regime).
Millerlake soils: have horizons of carbonate accumulation at depths of 15 to 40 inches.
Southmount soils: have O horizons and a mean summer temperature of 48 to 52 degrees F.
Stubbs soils: have a paralithic contact at depths of 20 to 40 inches.
GEOGRAPHIC SETTING:
Parent material: glacial drift, colluvium, and slope alluvium derived mainly from snadstone,
shale, andesite, and some basalt.
Landform: plateaus, hills, and mountain slopes.
Slopes: 2 to 65 percent
Elevation: 6,500 to 11,000 feet
/~'t Mean annual air temperatwe: about 40 degrees F.
Mean summer air temperature: about 58 degrees F.
Mean annual precipitation: 20 to 45 inches.
Frost-free period: 50 to 80 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Baird Hollow, Flv¢are and
Sessions soils.
Baird Hollow and Flygare soils: have albic horizons, and the upper boundary of the argillic
horizon is below 24 inches.
Sessions soils: have more than 35 percent clay in the panicle size control section.
DRAINAGE AND PERMEABII.ITY: Well drained; Jow to high runoff, moderate or
moderately slow permeability.
USE AND VEGETATION: These soils are used for watershed and rangeland from late spring
through fall for livestock and wildlife grazing. Native vegetation consists of mountain
bromegrass, oniongrass, slender wheatgrass, sagebrush, western wheatgrass and bluegrass.
