TYPE LOCATION: Park County, Colorado; about 16 miles east of Hartsel, about 2,400 feet north and 100 feet west of the southeast corner of Sec. 8, T. 12 S., R. 73 W.; Glentivar USGS quad; latitude 39 degrees, 1 minute, 19 seconds N.; longitude 105 degrees, 34 minutes, 30 seconds W., NAD 83.
RANGE IN CHARACTERISTICS:
Soil moisture: The soil moisture control section is usually dry in late spring and early summer, moist in some part in late July and August, and intermittently dry in fall; ustic regime bordering on aridic.
Mean annual soil temperature: 37 to 41 degrees F.
Mean summer soil temperature: 51 to 58 degrees F.
Thickness of mollic epipedon: 7 to 15 inches
Sands are angular to subrounded and include a high proportion of quartzite and micas
Particle-size control section (weighted average):
Clay content: 5 to 8 percent
Rock fragment content: 35 to 45 percent
A horizon
Hue: 10YR, 7.5YR
Value: 4 or 5 dry; 2 or 3 moist
Chroma: 2 to 4 dry; 2 or 3 moist
Clay content: 10 to 18 percent
Gravel content: 5 to 14 percent
Organic matter content: 2.0 to 4.0 percent
AC horizon
Hue: 10YR, 7.5YR
Value: 4 to 6 dry; 3 to 5 moist
Chroma: 2 to 4 dry; 2 to 4 moist
Texture: gravelly sandy loam, gravelly loamy coarse sand
Clay content: 5 to 19 percent
Gravel content: 15 to 35 percent
C horizons
Hue: 10YR, 7.5YR
Value: 5 to 7 dry; 4 to 6 moist
Chroma: 3 to 6 dry; 3 to 6 moist
Texture: very gravelly coarse sand, gravelly coarse sand
Clay content: 1 to 8 percent
Fragment size and content: 15 to 60 percent indurated gravel; 0 to 3 percent indurated cobbles; 0 to 1 percent indurated stones
Reaction: neutral or slightly alkaline (pH 6.6 to 7.8)
COMPETING SERIES: These are the
Bearmouth,
Pierian, and
Tine series.
The Bearmouth and Tine soils have a lithologic discontinuity, and do not border an aridic moisture regime.
The Pierian soils have greater than 1 percent stones, and do not border an aridic moisture regime.
GEOGRAPHIC SETTING:
Parent material: alluvium derived from mixed sources
Landform: alluvial fans, bajadas
Slopes: 1 to 12 percent
Elevation: 8,700 to 9,800 feet
Mean annual temperature: 35 to 39 degrees F.
Mean annual precipitation: 10 to 14 inches
Precipitation pattern: Monthly precipitation is lowest in winter and greatest in July and August.
Frost-free period: 50 to 80 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gebson and Levenmile soils. These soils have a lower gravel content, and the fine-earth fraction of the substratum averages sandy loam or finer. The Gebson soils have argillic horizons.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; moderately rapid permeability.
USE AND VEGETATION: These soils are used for livestock grazing. Native vegetation consists of Arizona fescue, slimstem muhly, prairie junegrass, blue grama, bottlebrush squirreltail, needleandthread, and western wheatgrass.
DISTRIBUTION AND EXTENT: Intermontane basins and valleys of Central Colorado; LRR E, MLRA 48B. The series is of moderate extent.
