TYPE LOCATION: Washakie County, Wyoming; 600 feet south, 40 feet west of the NE corner of sec. 13, T. 45 N., R. 92 W.
RANGE IN CHARACTERISTICS: Depth to bedrock is 20 to 40 inches. The mean annual soil temperature is 47 to 52 degrees F. Rock fragments less than 3 inches in diameter range from 0 to 10 percent.
The A horizon has hue of 2.5Y or 10YR, value of 5 through 7 dry, 4 through 6 moist, and chroma of 2 or 3. This horizon is neutral to moderately alkaline.
The Bt horizon has hue of 10YR or 7.5YR, value of 5 or 6 dry, 3 through 5 moist, and chroma of 2 through 4. It is sandy clay loam or clay loam and averages 15 to 35 percent fine or coarser sand. This horizon is slightly to strongly alkaline.
The C horizon has hue of 2.5Y or 10YR, value of 6 or 7 dry, 3 through 6 moist, and chroma of 2 through 4. It is sandy loam, sandy clay loam, or clay loam, and less commonly silty clay loam. This horizon is moderately or strongly alkaline.
COMPETING SERIES: These are the Bacobi, Friste, Fruita, Fruitvale, Grazane, Grieta, Griffy, Kiki, Papoose, Redlands, Saddle, Starmountain, and Tijeras series. Bacobi and Grazane soils have average annual soil temperature above 52 degrees F. Frisite, Fruita, Fruitvale, Grieta, Griffy, Papoose, Redlands, Starmountain, and Tijeras soils are very deep. Kiki soils are moderately deep to a lithic contact. Saddle soils have more than 35 percent fine or coarser sand in the Bt horizon.
GEOGRAPHIC SETTING: Neiber series are on upland back slopes and foot slopes. Slopes are 3 to 30 percent. The soils formed in residuum or locally transported material weathered from soft, calcareous sandstone interbedded with shale. Elevation is 4,000 to 5,500 feet. The mean annual precipitation is 6 to 9 inches. The mean annual temperature is 44 to 51 degrees F. The frost-free season is 110 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Fruita and Saddle soils.
DRAINAGE AND PERMEABILITY: Well drained; slow to moderate runoff; moderate permeability.
USE AND VEGETATION: These soils are used mainly for rangeland and wildlife habitat. Native vegetation is bluegrama, Gardner saltbush, bud sagebrush, western wheatgrass, Sandberg bluegrass, and big sagebrush.
DISTRIBUTION AND EXTENT: In the Big Horn Basin of north-central Wyoming. The series is of moderate extent.
