WAGORE SERIES

The Wagore series consists of very deep, well drained soils that formed in colluvium derived from granitic rocks with surficial additions of loess. Wagore soils are on mountains. Slopes are 30 to 50 percent. The mean annual precipitation is about 330 mm and the mean annual temperature is about 6 degrees C.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, frigid Pachic Haploxerolls

TYPICAL PEDON: Wagore gravelly loam--rangeland. (Colors are for dry soil unless otherwise noted.) The soil surface is partially covered with 3 percent stones, 5 percent cobbles, and 10 percent gravel.

A--0 to 13 cm; dark grayish brown (10YR 4/2) gravelly loam, very dark brown (10YR 2/2) moist; strong fine subangular blocky structure; soft, very friable, slightly sticky and slightly plastic; many very fine and fine roots; many very fine, fine and medium tubular and interstitial pores; 15 percent gravel and 3 percent stones; neutral (pH 6.6); clear smooth boundary. (10 to 20 cm thick)

Bw1--13 to 30 cm; dark grayish brown (10YR 4/2) gravelly loam, dark brown (7.5YR 3/2) moist; strong medium and coarse subangular blocky structure; soft, very friable, slightly sticky and slightly plastic; many very fine, fine and medium roots; many very fine, fine and medium tubular and interstitial pores; 20 percent gravel; neutral (pH 6.6); clear smooth boundary. (13 to 25 cm thick)

Bw2--30 to 58 cm; yellowish brown (10YR 5/4) gravelly coarse sandy loam, dark brown (10YR 3/3) moist; weak fine subangular blocky structure; slightly hard, friable, slightly sticky and nonplastic; many very fine, fine and medium roots; common very fine and fine tubular and interstitial pores; 30 percent gravel; neutral (pH 6.8); clear smooth boundary. (20 to 46 cm thick)

C1--58 to 102 cm; yellowish brown (10YR 5/4) gravelly coarse sandy loam, dark yellowish brown (10YR 4/4) moist; massive; slightly hard, friable, slightly sticky and nonplastic; common very fine and fine, few medium roots; common very fine and fine tubular pores; 30 percent gravel; neutral (pH 7.0); clear smooth boundary. (38 to 64 cm thick)

C2--102 to 157 cm; pale brown (10YR 6/3) gravelly coarse sandy loam, brown (10YR 4/3) moist; massive; slightly hard, friable, slightly sticky and nonplastic; common very fine and fine, few medium roots; common very fine and fine tubular pores; 30 percent gravel; neutral (pH 7.0).

TYPE LOCATION: Washoe County, Nevada; in the Miller Basin area of the Granite Range; approximately 2,400 feet south and 1,000 feet east of the northwest corner of section 14, T. 34 N., R. 22 E.; USGS The Banjo 7.5 minute topographic quadrangle; latitude 40 degrees 50 minutes 0.4 seconds north and longitude 119 degrees 27 minutes 47.0 seconds W; WGS84 Decimal Degrees 40.8334444 latitude, -119.4630556 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually moist in winter, spring, and early summer, dry from mid-July through mid-October for 80 to 100 days; aridic soil moisture regime that borders on xeric.
Mean annual soil temperature: 6 to 8 degrees C.
Mollic epipedon thickness: 50 to 76 cm.
Depth to bedrock: 150 to 200 cm to a paralithic contact of weathered granitic rock.
Reaction: Slightly acid or neutral.

Particle-size control section - Clay content: 10 to 18 percent.
Rock fragments: 15 to 35 percent, over one-half of which are fine (2 to 5 mm diameter) granitic gravel.

A horizon
Value: 4 or 5 dry, 2 or 3 moist.
Chroma: 2 or 3, dry or moist.

Bw1 and Bw2 horizons
Value: 4 or 5 dry, 2 or 3 moist.
Chroma: 2 through 4 dry, 2 or 3 moist, may be 4 moist in lower part.
Texture: Gravelly sandy loam or gravelly coarse sandy loam; some pedons have texture of gravelly loam in the Bw1 horizon.
Clay content: 10 to 18 percent.
Rock fragments: 15 to 35 percent.

C1 and C2 horizons
Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 through 4, dry or moist.
Texture: Mainly gravelly coarse sandy loam with some pedons having gravelly sandy loam in the C1 horizon.
Clay content: 10 to 18 percent.
Rock fragments: 15 to 35 percent.

COMPETING SERIES: These are the Cinderspring, Iver, Kabear, Lobert, Ola, Prucree, Redmount, Shively, Suryon, and Taterpa series.

Cinderspring, Redmount and Suryon soils are not dominated by fine granitic gravel in the particle-size control section and have a xeric moisture regime. Iver soils have silty texture in the upper part of the particle-size control section and more than 35 percent rock fragments in the lower part of the particle-size control section. Kabear soils have less than 15 percent rock fragments in the particle-size control section. Lobert soils have less than 15 percent rock fragments in the particle-size control section and have durinodes in horizons below the particle-size control section. Ola and Prucree soils are moderately deep to paralithic contacts. Shively soils are deep to paralithic contacts, average less than 15 percent rock fragments, and are not dominated by fine granitic gravel in the particle-size control section. Taterpa soils are deep to paralithic contacts and have a xeric moisture regime.

GEOGRAPHIC SETTING: Wagore soils are on mountains. They typically occur on backslope positions. These soils formed in colluvium derived from granitic rocks with surficial additions of loess. Slopes are 30 to 50 percent. Elevations range from 1,465 to 2,380 meters. The climate is semiarid with cold, moist winters and warm, dry summers. The mean annual precipitation is 300 to 360 mm, the mean annual temperature is 5 to 7 degrees C, and the frost-free period is 50 to 75 days.

GEOGRAPHICALLY ASSOCIATED SOILS: This is the Eaglerock soil. Eaglerock soils have an argillic horizon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; medium surface runoff; high saturated hydraulic conductivity.

USE AND VEGETATION: Wagore soils are used for rangeland and wildlife habitat. The present vegetation is mainly mountain big sagebrush, bluegrass, mountain brome, bluebunch wheatgrass, lupine, green rabbitbrush, and snowberry.

DISTRIBUTION AND EXTENT: Northwestern Nevada. These soils are not extensive with about 1,500 acres of the series mapped to date. MLRA 23.
