Fish Creek Soil Investigation
<br />The C horizon, if present, has value of 5 or 6 dry, 4 or 5 moist, and chroma of 3 or 4.
<br />• COMPETING SERIES: These are the Adel (MT),(T) Bullbasin (CO), Bullrev (ID), Duff (NV),
<br />Gallatin (MT), Hackwood (NV), (T)Idmon (ID), Karlan (ID), Lamphier (CO), Leavittville (WY),
<br />(T) Lespate (CO), Mundos (WY), Osmund (WY), Pavohroo (ID), Rhone (CO), (T) Secondset
<br />(CO), Strictland (CO), and (T) Taterheap (CO) soils. The Adel, Bullbasin, Bullrey, Duff,
<br />Gallatin, Hackwood, Idmon, Karlan, Lamphier, Leavittville, Mundos, Osmund, Pavohroo,
<br />Rhone, and Taterheap soils lack bedrock above 40 inches. Karlan, Leavittville, Lespate, Mundos,
<br />and Osmund soils have K horizons. Secondset soils have moisture control sections that are moist
<br />for longer cumulative periods when the soil temperature at 20 inches is greater than 41 degrees F.
<br />Strictland soils have clay movement and accumulation in an insipient Bt horizon with clay films
<br />on the peds.
<br />GEOGRAPHIC SETTING: Winevada soils are on plateaus and mountain slopes. Slopes range
<br />from 3 to 70 percent. The soil formed in residuum and colluvium derived from sandstone.
<br />Elevation is 6,500 to 8,500 feet. The mean annual precipitation ranges from 18 to 25 inches.
<br />Mean annual temperature is 37 to 42 degrees F. Frost -free period is 40 to 75 days.
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Coutis, Foidel, SRlitro, and
<br />Rhone soils. Coutis, Foidel, and Rhone soils are deep. Splitro soils are shallow to a lithic contact.
<br />DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff; moderate
<br />permeability.
<br />USE AND VEGETATION: These soils are used for livestock grazing and wildlife habitat.
<br />Native vegetation consist of Letterman needlegrass, slender wheatgrass, mountain brome, elk
<br />sedge, sagebrush, serviceberry, snowberry, and Gambel oak.
<br />DISTRIBUTION AND EXTENT: These soils occur in northwestern Colorado. The series is of
<br />moderate extent. Total area is about 11,000 acres.
<br />MLRA OFFICE RESPONSIBLE: Lakewood, Colorado
<br />SERIES ESTABLISHED: BLM Sonoma Planning Unit, Nevada, 1974.
<br />REMARKS: The diagnostic horizons recognized in this pedon are the mollic epipedon - the
<br />zone from 0 to 24 inches, and the lithic contact at 30 inches. The type location and series
<br />responsibility was moved from Nevada to Colorado in 1989. Last update by the state 12/90.
