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 Ade] (MT),(T) Bullbasin (CO), Bullrev (ID), Duff (NV),
<br />Gallatin (MT}, Hackwood (NV), (T)Idmon (ID), Kazlan (ID), Lamphier (CO}, Leavittville (WY),
<br />(T) Lesnate (CO), Mundos (Wl~, Osmund (WY), Pavohroo (ID), Rhone (CO), (T) Secondset
<br />(CO), Strictland (CO), and (T) Taterhean (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 aze moist
<br />for longer cumulative periods when the soil temperature at 20 inches is greater than 41 degrees
<br />F. Strictland soils have clay movement and accumulation in an incipient Bt horizon with clay
<br />films on the peds.
<br />GEOGRAPffiC SETTING: Winevada soils aze 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 I S to 25 inches.
<br />Mean annual temperatwe is 37 to 42 degrees F. Frost-free period is 40 to 75 days.
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Coutis. Foidel. S~litro. and
<br />Rhone soils. Coutis, Foidel, and Rhone soils are deep. Splitro soils are shallow to a lithic
<br />contact.
<br />DRAINAGE AND PERMEABII.TTY: Well drained; medium to rapid runoff; moderate
<br />permeability.
<br />USE AND VEGETATION: These soils aze used for livestock grazing and wildlife habitat.
<br />Native vegetation consist of Letterman needlegrass, slender wheatgrass, mountain brome, elk
<br />sedge, sagebrush, serviceberry, snowbeny, 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 aze 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 ]2/90.
