REDCAMERON SERIES


The Redcameron series consists of shallow or very shallow, well drained soils. These soils formed in residuum and colluvium derived from sandstone and siltstone on mountain slopes, ridges, and hogbacks. Slopes range from 20 to 55 percent. Mean annual temperature is about 45 degrees F., and the mean annual precipitation is about 13 inches.

TAXONOMIC CLASS: Loamy, mixed, superactive, calcareous, frigid Lithic Ustic Torriorthents

TYPICAL PEDON: Redcameron channery loam - on a 20 percent slope in an area of pinyon and juniper. (Colors are for dry soil unless otherwise stated.)

A--0 to 2 inches; pinkish gray (7.5YR 6/2) channery loam, dark brown (7.5YR 3/2) moist; weak coarse platy structure; soft, very friable, slightly sticky and nonplastic; 25 percent channers; strongly effervescent; moderately alkaline; abrupt smooth boundary.

C--2 to 12 inches; pinkish gray (7.5YR 6/2) channery very fine sandy loam, brown (7.5YR 4/2) moist; massive; soft, very friable, slightly sticky and nonplastic; 20 percent channers; strongly effervescent; moderately alkaline; abrupt smooth boundary.

R--12 inches; hard red sandstone.

TYPE LOCATION: Fremont County, Colorado; about 900 feet north and 2,200 feet west of the southeast corner of Sec. 14, T. 49 N., R. 10 E. U.S.G.S. Howard quad.; Lat. 38 degrees, 29 minutes, 34 seconds N., and Long. 105 degrees, 49 minutes, 54 seconds W.

RANGE IN CHARACTERISTICS: The mean annual soil temperature ranges from 44 to 47 degrees F. The mean summer soil temperature ranges from 59 to 65 degrees F. Depth to bedrock ranges from 4 to 20 inches. These soils are calcareous throughout. The particle-size control section of the fine-earth is very fine sandy loam, fine sandy loam, or loam, and averages 8 to 18 percent clay. Sandstone channer content ranges from 0 to 35 percent. The moisture control section in most years is dry in some parts more than one-half the time when the soil temperature is above 41 degrees F., but in most years is moist in some parts more than 60 consecutive days in late summer and early fall.

The A horizon has hue of 5YR through 10YR, value of 5 or 6 dry, 3 through 5 moist and chroma of 2 through 4. It is slightly alkaline or moderately alkaline.

The C horizon has hue of 5YR through 10YR, value of 5 through 7 dry, 4 or 5 moist and chroma of 2. Reaction is moderately alkaline.

COMPETING SERIES: These are the Redcreek (WY), and Yellowwash (CO) series.

Redcreek soil is moist in some part of the moisture control section for a minimum of 45 consecutive days and is dry in all parts by July 15 during the summer months. It is moist during April, May, and early June when precipitation is at a peak.

Yellowwash soils have 18 to 27 percent clay in the particle-size control section and have hue of 10YR and yellower.

GEOGRAPHIC SETTING: Redcameron soils are on mountain slopes, ridges, and hogbacks. Slopes range from 20 to 55 percent. The soils formed in residuum and colluvium derived from sandstone and siltstone. Elevation ranges from 7,400 to 8,500 feet. The mean annual temperature is 43 to 46 degrees F., and the mean annual precipitation is about 12 to 15 inches.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brownell and Teaspoon soils. The Brownell soils are deep, and the Teaspoon soils have an argillic horizon with greater than 35 percent rock fragments by volume.

DRAINAGE AND PERMEABILITY: Well drained; rapid runoff; moderately rapid permeability.

USE AND VEGETATION: These soils are used for noncommercial woodland, wildlife habitat, and livestock grazing. Principal vegetation is an overstory of pinyon pine and juniper and an understory of blue grama, Scribner needlegrass, true mountain mahogany, Indian ricegrass, and sideoats grama.

DISTRIBUTION AND EXTENT: In the foothills of the Eastern and Southern Rocky Mountains of central Colorado. The series is of small extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana

SERIES ESTABLISHED: Fremont County (Fremont County Area), Colorado, 1988.

REMARKS: Diagnostic horizons and features in this soil include an ochric epipedon; a lithic contact at 12 inches; and a texture control section with 8 to 18 percent clay; an ustic aridic moisture regime; and a frigid temperature regime. Last updated by the state 8/95.

The superactive cation exchange activity class was added in 03/2003 to the taxonomic classification by the National Soil Survey Center on request of the Lakewood MLRA office, without review of the soil series property data. The remainder of this document has not been updated.
