TYPE LOCATION: Johnson County, Wyoming; 500 feet north and 650 feet west of the southeast corner of sec. 3, T. 41 N., R. 77 W. Taylor Ranch Quadrangle. 43 degrees 32 minutes 46 seconds north latitude and 106 degrees 5 minutes 20 seconds west longitude.
RANGE IN CHARACTERISTICS: Depth to the paralithic contact ranges from 20 to 40 inches. The soil is 80 to 100 percent base-saturated. Gravel ranges from 0 to 15 percent but is usually less than 5 percent. The mean annual soil temperature ranges from 47 to 54 degrees F. The moisture control section is dry for 60 consecutive days and 90 cumulative days between July 15 and October 25 in most years.
The A horizon has hue of 2.5Y or 10YR, value of 5 to 7 dry and 3 to 5 moist, and chroma of 2 or 3. It typically has granular primary structure but has subangular blocky structure in some pedons. It is slightly acid to slightly alkaline.
The Bt horizon has hue of 2.5YR, 10YR or 7.5YR, value of 5 or 6 dry and 3 to 5 moist, and chroma of 2 to 4. This horizon is typically light sandy clay loam, but clay ranges from 18 to 35 percent, silt from 5 to 30 percent, and sand from 40 to 75 percent with more than 35 percent fine or coarser sand. It is neutral or slightly alkaline.
The C horizon has hue of 2.5Y or 10YR, value of 5 or 6 dry and 4 or 5 moist, and chroma of 3 or 4. Reaction is neutral to moderately alkaline.
COMPETING SERIES: These are the Balon, Blancot, Bowbac, Buckle, Cambria, Cushman, Decolney, Doakum, Forkwood, Gaddes, Gapmesa, Hagerman, Hagerwest, Hiland, Los Alamos, Mentmore, Oelop, Olney, Palacid, Penistaja, Pokeman, Potts, Quagwa, Redpen, Spangler, Spenlo, Sundance, Teckla and Yenlo soils. Balon, Blancot, Buckle, Cambria, Decolney, Doakum, Forkwood, Hiland, Los Alamos, Mentmore, Oelop, Olney, Palacid, Penistaja, Potts, Quagwa, Redpen, Spenlo, Sundance, Teckla and Yenlo series are more than 60 inches deep to paralithic beds. Bowbac, Cushman and Pokeman soils are calcareous at depths of less than 40 inches and have less than 35 percent fine or coarser sand. Gapmesa, Hagerman and Hagerwest soils have a lithic contact at depths of less than 40 inches. Gaddes soils are intermittently moist in the moisture control section between July 15 and October 25.
GEOGRAPHIC SETTING: The Pugsley soils are on ridges and hills. Slopes range from 1 to 15 percent. Elevation is 4,000 to 5,500 feet. The soils formed in alluvium and residuum. The average annual precipitation is 10 to 14 inches of which about half falls in April, May, and early June. The average annual air temperature is 46 degrees F. The frost-free season is 110 to 130 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Decolney soils and the Maysdorf, Parmleed, Renohill and Ulm soils. Maysdorf and Ulm soils are deeper than 60 inches to bedrock. Parmleed and Renohill soils are fine textured and have continuous horizons of secondary carbonate accumulation.
DRAINAGE AND PERMEABILITY: Well drained; medium or low runoff; moderate permeability.
USE AND VEGETATION: These soils are used principally for livestock grazing. Some small areas are used for dry cropland. Native vegetation is mainly needleandthread, prairie sandreed and Indian ricegrass.
DISTRIBUTION AND EXTENT: North central and northeastern Wyoming. The series is of moderate extent.
