TYPE LOCATION: Nye County, Nevada; approximately 16 miles northwest of the town of Beatty, about 5,000 feet east and 4,000 feet south of the approximate northwest corner of section 26, T. 9 N., R. 45 E.
RANGE IN CHARACTERISTIC:
Soil moisture - Usually dry, but moist in some horizon for short periods during winter and spring month, and for short intermittent periods following summer convection storms.
Soil temperature - 65 to 67 degrees F.
Depth to duripan - 20 to 40 inches.
Reaction - Moderately alkaline or strongly alkaline.
Cementation - All profiles contain some pan fragments in a horizon above the duripan. Some profiles contain cemented masses or a few durinodes.
Control section - Clay content: 5 to 18 percent, by average.
Rock fragments: 0 to 10 percent.
A horizon - Value: 6 or 7 dry, 5 or 6 moist.
Chroma: 3 or 4 dry, 4 or 5 moist.
Structure: Platy or subangular blocky.
C and Cq horizons - Value: 6 through 8 dry, 5 through 8 moist.
Chroma: 2 through 4 dry, 3 through 6 moist.
Texture: Stratified loam, sandy loam, or coarse sandy loam.
Clay content: 5 to 18 percent.
Rock fragments: 0 to 10 percent.
Structure: Subangular blocky, platy or massive.
Effervescence: Slightly effervescent or violently effervescent.
Cqkm horizon - Chroma: 1 through 3 dry, 2 through 4 moist.
Other features: Discontinuous thin laminar cap 1 to 4 mm thick which grades to strongly cemented then weakly cemented layers below.
COMPETING SERIES: There are no competing series. Shamock soils are similar but have an indurated duripan.
GEOGRAPHIC SETTING: Wanomie soils are on relict alluvial flats and fan piedmonts. These soils formed in alluvium from mixed rock sources. Slopes are 0 to 4 percent. Elevations are 2,600 to 5,200 feet. The winters are cool and the summers are hot and dry. The mean annual precipitation is about 6 to 9 inches. The mean annual temperature is about 58 to 62 degrees F.; the frost-free season is about 210 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Canutio and Seaman soils. The Canutio soils has a loamy-skeletal control section and the Seaman soils have no pan to a depth of 60 inches.
DRAINAGE AND PERMEABILITY: Well drained. Very slow or slow runoff; moderate permeability.
USE AND VEGETATION: Rangeland and wildlife habitat. The present vegetation is mainly ephedra, littleleaf horsebrush, and shadscale.
DISTRIBUTION AND EXTENT: Southern Nye County, Nevada. These soils are not extensive. MLRA 30.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California
SERIES PROPOSED: Nye County, Nevada. (Southwest part) 1983. The name is coined from a former mining town on the Nellis Bombing Range.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Entic feature - The strongly cemented zone from 30 to 31 inches.
Particle-size control section - The zone from 10 to 30 inches.
