HAULINGS SERIES

The Haulings series consists of very deep, very poorly drained soils that formed in alluvium derived from basic and intermediate igneous rocks. Haulings soils occur on flood plains and have slopes of 0 to 2 percent. The average annual precipitation is about 12 inches (305 mm) and the mean annual air temperature is about 44 degrees F (6.7 degrees C).

TAXONOMIC CLASS: Fine-loamy over sandy or sandy-skeletal, mixed, superactive, frigid Histic Endoaquolls

TYPICAL PEDON: Haulings muck, rangeland. (Colors are for moist soil unless otherwise noted.)

Oa--0 to 12 inches (0 to 30 cm); very dark brown (10YR 2/2) moist broken face; muck (sapric material), black (10YR 2/1) (rubbed and pressed); about 25 percent fiber, about 15 percent fiber after rubbing, moderate fine, medium and coarse subangular blocky structure; slightly sticky and slightly plastic; many fine and common medium roots throughout and forming a dense mat in the upper part; many very fine pores; strongly effervescent; moderately alkaline (pH 8.4); gradual wavy boundary. (9 to 10 inches (23 to 25 cm) thick)

A--12 to 33 inches (30 to 84 cm); black (10YR 2/1) loam; weak fine granular structure; hard, friable, slightly sticky and slightly plastic; many fine and common medium roots; common fine and medium pores; slightly alkaline (pH 7.4); gradual wavy boundary. (9 to 26 inches (23 to 66 cm) thick)

Cg--33 to 38 inches (84 to 96 cm); dark grayish brown (2.5Y 4/2) clay loam; many medium distinct and dominant olive brown (2.5Y 4/4) and dark reddish brown (2.5YR 2.5/4) redoximorphic concentrations; massive; very hard, firm, moderately sticky and moderately plastic; few fine roots; few fine pores; neutral (pH 7.2); clear smooth boundary. (5 to 12 inches (13 to 31 cm) thick)

2C--38 to 72 inches (96 to 183 cm); very dark grayish brown (10YR 3/2) very gravelly coarse sand; single grain; interstitial pores; 30 percent gravel and 5 percent cobbles; neutral (pH 6.8).

TYPE LOCATION: Sevier County, Utah; 0.75 mile northeast of Koosharem Reservoir Dam; 1,300 feet east and 700 feet north of SW corner of section 29, T.25S., R.1E., SLBM.; USGS Burrville 7.5 minute quadrangle; lat. 38 degrees 36 minutes 4.3 seconds N. and long. 111 degrees 49 minutes 34 seconds W.; NAD 83.

RANGE IN CHARACTERISTICS:

Soil moisture: Usually wet in some part of the moisture control section. (Aquic moisture regime.)
Water table: Depth is 0 to 30 cm., kind is apparent, months are January to December.
Mean annual soil temperature: 40 to 46 degrees F (4.4 to 7.8 degrees C)
Mean summer soil temperature: 59 to 63 degrees F (15.0 to 17.2 degrees C)
Thickness of the histic epipedon: 8 to 12 inches (20 to 30 cm)
Thickness of the mollic epipedon: 20 to 36 inches (50 to 91 cm)

Particle-size control section:
Clay content: 18 to 35 percent in the upper part; 2 to 5 percent in the lower part
Rock fragments: 0 percent in the upper part; 15 to 59 percent in the lower part, mainly gravel.

A horizon:
Value: 3 or 4 dry, 2 or 3 moist
Chroma: 1 or 2
Textures: Loam or mucky loam
Reaction: Neutral to slightly alkaline

Cg horizon:
Hue: 2.5Y or 10YR
Value: 5 or 6 dry and 3 or 4 moist
Chroma: 1 or 2
Texture: Loam or clay loam
Clay content: 18 to 35 percent
Redox feature: Common to many distinct or prominent redoximorphic concentrations
Reaction: Neutral to slightly alkaline

2C horizon:
Value: 5 through 7 dry, 3 or 4 moist
Chroma: 1 or 2
Texture: Very gravelly or gravelly sand or coarse sand
Reaction: Neutral to slightly alkaline

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: The Haulings soils are at elevations of 5,800 to 7,560 feet (1,768 to 2,304 m). Slopes are 0 to 2 percent. The soils occur on flood plains and formed in alluvium derived mainly from basic and intermediate igneous rocks. The climate is semiarid, the average annual precipitation is 11 to 16 inches (279 to 406 mm). The mean annual air temperature is 39 to 45 degrees F (3.9 to 7.2 degrees C), and the freeze-free period is 70 to 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dacore, Jodero and Krueger soils. Dacore soils have argillic and calcic horizons and are on alluvial fans. Jodero soils have an irregular decrease in organic carbon with depth. Krueger soils lack a histic epipedon and have an argillic horizon. All are well drained and have mollic epipedons.

DRAINAGE AND PERMEABILITY: Very poorly drained; ponded or low runoff; moderately slow permeability; Ksat class is moderately high.

USE AND VEGETATION: These soils are used for pasture and wildlife habitat. The native vegetation is wiregrass, broadleaf sedges and spike rush.

DISTRIBUTION AND EXTENT: Central Utah, Grass Valley area in Sevier and Piute Counties; MLRA 47. The series is inextensive.
