GOL SERIES

The Gol series consists of shallow, well drained soils that formed in residuum derived from granitic rocks. Gol soils are on mountain side slopes. Slopes are 4 to 75 percent. The mean annual precipitation is about 230 mm and the mean annual temperature is about 7 degrees C.

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, frigid, shallow Xeric Haplargids

TYPICAL PEDON: Gol very bouldery sandy loam--rangeland. (Colors are for dry soil unless otherwise noted).

A1--0 to 8 cm; pale brown (10YR 6/3) very bouldery sandy loam, dark grayish brown (10YR 4/2) moist; moderate very fine platy structure; soft, friable, slightly sticky and slightly plastic; common very fine and few fine roots; many very fine and few fine vesicular pores; 15 percent gravel, 20 percent cobbles and 15 percent boulders; slightly alkaline (pH 7.8); clear smooth boundary. (5 to 13 cm thick)

A2--8 to 21 cm; pale brown (10YR 6/3) sandy loam, dark grayish brown (10YR 4/2) moist; weak, very fine platy structure; soft, friable, slightly sticky and slightly plastic; common very fine and few fine roots; common very fine tubular pores; 10 percent gravel; slightly alkaline (pH 7.8); clear smooth boundary. (8 to 13 cm thick)

BA--21 to 30 cm; brown (10YR 5/3) very gravelly loam, brown (10YR 4/3) moist; moderate fine subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; common very fine roots; few very fine and fine tubular pores; 30 percent gravel and 5 percent cobbles; slightly alkaline (pH 7.6); clear smooth boundary. (0 to 18 cm thick)

Bt--30 to 46 cm; yellowish brown (10YR 5/4) very gravelly clay loam, brown (10YR 4/3) moist; moderate fine and medium subangular blocky structure; slightly hard, firm, slightly sticky and slightly plastic; common very fine and few fine and medium roots; common very fine and few fine tubular pores; 40 percent gravel and 5 percent cobbles; common thin clay films on faces of peds and lining pores; slightly alkaline (pH 7.6); abrupt wavy boundary. (13 to 25 cm thick)

Cr--46 cm; soft weathered granite.

TYPE LOCATION: Pershing County, Nevada; Granite Mountain area in the southern part of the East Range, about 500 feet north and 900 feet west of the southeast corner of section 15, T. 28 N., R. 37 E.; latitude 40 degrees 17 minutes 31 seconds N and longitude 117 degrees 47 minutes 56 seconds W; WGS84 Decimal Degrees 40.2919444 latitude, -117.79889 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually dry, moist in winter and spring, dry from mid-June through October; aridic soil moisture regime bordering on xeric.
Mean annual soil temperature: 7 to 8 degrees C.
Depth to weathered bedrock: 36 to 50 cm.
Reaction: Neutral or slightly alkaline.
Other features: Noncalcareous throughout.

Particle-size control section - Clay content: 18 to 35 percent.
Rock fragments: 35 to 50 percent, dominantly gravel that are primarily 2 to 5 mm in size.

A horizon
Value: 5 through 7 dry.
Chroma: 2 or 3.

Bt horizon
Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 through 4.
Texture: Very gravelly loam, very gravelly clay loam, very gravelly sandy clay loam.
Structure: Subangular blocky, or the horizon is massive.
Consistence: Friable or firm, moist; slightly plastic or plastic, wet.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Gol soils are on side slopes of mountains. These soils formed in residuum derived from granitic rocks. Slopes are 4 to 75 percent. Elevations are 1,525 to 2,135 meters. The climate is cool, semiarid with cold, moist winters and warm, dry summers. The mean annual precipitation is 200 to 300 mm, mean annual temperature is 6 to 7 degrees C, and the frost-free period is 80 to 110 days.

GEOGRAPHICALLY ASSOCIATED SOILS: This is the Say soils. The Say soils are greater than 50 cm deep.

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

USE AND VEGETATION: Livestock grazing and wildlife habitat. The present vegetation is mainly Wyoming sagebrush, Thurber needlegrass, Sandberg bluegrass, bluebunch wheatgrass and bottlebrush squirreltail.

DISTRIBUTION AND EXTENT: North-central Nevada. Gol soils are of small extent. MLRA 24,27.
