Fish Creek Soil Investigation
RANGE IN CHARACTERISTICS: The 10- to 40-inch control section is normally clay or silty
S clay, but percent of clay ranges from 35 to 60. Rock fragments range from 0 to 25 percent by
volume in the major part of the control section. They aze mainly shale fragments of 1/2- to 3-inch
size. Cracks up to 1 inch or more wide occur when soils aze dry for 100 to I50 days. Cracks
extend to depths of 20 or more inches. Slickensides that intersect aze common to depths of 40
inches. The mean annual soil temperature ranges from 43 to 47 degrees F., and the mean summer
soil temperature ranges from 55 to 59 degrees F. Depth to calcareous material ranges 0 to 20
inches.
The A horizon has hue of SY through l OYR, value of 4 through 6 dry, and 4 or 5 moist, with
chroma of 2 through 4. Reaction is neutral through moderately alkaline.
The Bss horizon has hue of SY through l OYR, value of 4 through 7 dry, and 4 through 6 moist,
with chroma of 2 through 4. Reaction is mildly alkaline or moderately alkaline.
The Bk or C horizon has hue of SY through l OYR, value of 4 through 7 dry, 4 through 6 moist,
and chroma of 2 through 6.
COMPETING SERIES: These are the Aaberg (CO), Abor (MT), Bazkof (MT), Bascovy (MT),
(T)Bickerdyke (MT), Bulkley (CO), Dutton (MT), Gerber (MT), Linnet (MT), Macias (MT),
Marvan (MT), and Styers (CO) series. All of these soils except Aaberg have mean annual
summer soil temperatures warmer than 59 degrees F. Aaberg and Styers soils have a pazalithic
bedrock layer above 40 inches.
GEOGRAPHIC SETTING: Binco soils are on alluvial fans and mountain foot slopes. Slopes
are 0 to 45 percent. The soil formed in alluvium, colluvium, and residuum, and is derived from
sedimentary rocks. Elevation is 7,200 to 8,200 feet. At the type location the mean annual
precipitation ranges from 11 to 14 inches. In other colder azeas it ranges to 18 inches. The mean
annual air temperature is 37 to 43 degrees F. The frost-free season is 35 to 65 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These aze the competing Aaberg soils and the
Waybe soils. Waybe soils aze shallow to shale.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; slow permeability.
USE AND VEGETATION: These soils are used principally for range and wildlife. Native
vegetation consists of wheatgrasses, Indian ricegrass, greasewood, and big sagebrush.
DISTRIBUTION AND EXTENT: Mountainous azeas ofnorth-central Colorado. The series is
of minor extent.
MLRA OFFICE RESPONSIBLE: Lakewood, Colorado
SERIES ESTABLISHED: Grand County, Colorado, 1977.
REMARKS: Diagnostic features include a Bss horizon at 7 to 37 inches (Bssl and Bss2
horizons). Last updated by the state 12/90.
