GOLDRUN SERIES

The Goldrun series consists of very deep, somewhat excessively drained soils that formed in eolian and lacustrine sands derived from mixed rocks with some influence from volcanic ash. The Goldrun soils are on sand dunes and sand sheets. Slopes are 0 to 30 percent. The mean annual precipitation is about 200 mm and the mean annual temperature is about 9 degrees C.

TAXONOMIC CLASS: Mixed, mesic Xeric Torripsamments

TYPICAL PEDON: Goldrun loamy fine sand--rangeland. (Colors are for dry soils unless otherwise noted.)

A--0 to 18 cm; light brownish gray (10YR 6/2) micaceous loamy fine sand, dark grayish brown (10YR 4/2) moist; single grain; loose, nonsticky and nonplastic; many very fine and fine roots; many very fine and fine interstitial pores; moderately alkaline (pH 8.2); clear smooth boundary. (13 to 23 cm thick)

C1--18 to 61 cm; light brownish gray (10YR 6/2) fine sand, dark grayish brown (10YR 4/2) moist; massive; soft, very friable, nonsticky and nonplastic; many very fine and fine roots; many very fine and fine interstitial pores; moderately alkaline (pH 8.2); clear wavy boundary. (13 to 50 cm thick)

C2--61 to 107 cm; light gray (10YR 7/2) fine sand, grayish brown (10YR 5/2) moist; massive; soft, very friable, nonsticky and nonplastic; common very fine and fine roots; many very fine interstitial pores; appears to contain particles of ash; slightly effervescent; moderately alkaline (pH 8.4); clear wavy boundary. (15 to 50 cm thick)

C3--107 to 170 cm; light brownish gray (10YR 6/2) fine sand, brown (10YR 5/3) moist; single grain; loose, nonsticky and nonplastic; few very fine and fine roots; many very fine and fine interstitial pores; slightly effervescent; moderately alkaline (pH 8.4); abrupt wavy boundary. (30 to 71 cm thick)

2Ck--170 to 196 cm; light brownish gray (10YR 6/2) very gravelly and cobbly loamy fine sand, brown (10YR 5/3) moist; massive; soft, very friable; few very fine and fine roots; many very fine and fine interstitial pores; 50 percent rounded gravel and cobbles; stone line of cobbles and gravel at 170 cm; the cobbles and gravel have a thin white coating of lime; slightly effervescent; strongly alkaline (pH 9.0).

TYPE LOCATION: Humboldt County, Nevada; approximately 1/2 mile west of Bridge street on Haskell street and 50 feet south of Haskell street about 1,300 feet north and 500 feet east of the southwest corner of section 29 T. 36 N., R. 38 E; USGS Winnemucca East 7.5 minute topographic quadrangle; latitude 40 degrees 57 minutes 47 seconds N and longitude 117 degrees 44 minutes 02 seconds W; WGS84 Decimal Degrees 40.9630556 latitude, -117.733889 longitude.

RANGE IN CHARACTERISTICS: Soil moisture: Usually dry, moist in winter and spring, dry early June through October; aridic soil moisture regime bordering on xeric.
Mean annual soil temperature: 8 to 11 degrees C.
Depth to lime: 43 to 90 cm.
Other features: Some pedons have horizons with less than 15 percent durinodes or weak discontinuous silica bridging mineral grains.

Particle-size control section - Clay content: Averages 1 to 8 percent.

A horizon
Reaction: Neutral through moderately alkaline.

C horizon
Texture: Dominantly fine sand with strata of coarse sand, loamy sand or loamy fine sand common in some pedons.
Reaction: Neutral through strongly alkaline

2Ck horizon
Reaction: Moderately alkaline or strongly alkaline.
Carbonates: Slightly effervescent through strongly effervescent.

COMPETING SERIES: These are the Berent, Grandora, Hotsprings, Incy, Lachim, Painter, Quincy, Quinton, Rinquin, Toll, Walco, Winchester, and Zorravista series.

Berent soils have loamy fine sand particle-size control sections and are noncalcareous to depth of 90 cm or more. Grandora soils have clay films and lack effervescence. Hotsprings soils have a particle-size control section of gravelly loamy sand or gravelly loamy coarse sand with 20 to 35 percent fine gravel. Incy soils are noncalcareous throughout their profiles. Lachim, Painter, Quinton, Rinquin and Walco soils have bedrock at a depth of 50 to 100 cm. Quincy soils have dominantly dark basaltic mineral grains with moist values of 3 or 4 in the series control sections. Toll soils have loamy sands and are medium acid to neutral in the series control sections. Winchester soils have sand and loamy sand in the series control sections with more than 75 percent medium sand or coarser. Zorravista soils are strongly to weakly effervescent at depth of 0 to 50 cm and are strongly influenced by vitric pyroclastic materials.

GEOGRAPHIC SETTING: Goldrun soils are on sand dunes, beach plains, and sand sheets. These soils formed in eolian and lacustrine sands derived from mixed rocks with some influence from volcanic ash. Slopes are 0 to 30 percent. Elevations are 1,100 to 1,740 meters. The climate is cool, semiarid with cool moist winters and hot dry summers. The mean annual precipitation is 180 to 250 mm, mean annual temperature is 7 to 10 degrees C, and the frost-free season is 100 to 120 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Benin, McConnel, Orovada, Preble, Rad, Rebel, and Valmy soils. Benin soils have a fine particle-size control section. McConnel soils have a cambic horizon and a sandy-skeletal particle-size control section. Orovada soils have cambic horizons and coarse-loamy particle-size control section. Preble, Rebel and Valmy soils have coarse-loamy particle-size control sections. Rad soils have a coarse-silty particle-size control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained; very slow and slow runoff; high saturated hydraulic conductivity.

USE AND VEGETATION: Rangeland, wildlife habitat. The present vegetation is mainly Wyoming big sagebrush, rabbitbrush, hairy horsebrush, spiny hopsage, fourwing saltbush, needleandthread, Indian ricegrass, cheatgrass and scurfpea.

DISTRIBUTION AND EXTENT: North-central Nevada. These soils are not extensive. MLRA 24, 27.
