JOEGALE SERIES

The Joegale series consists of shallow, well drained soils that formed in slope alluvium over residuum weathered from calcareous sandstone and limestone. These soils are on shoulders and summits of hillslopes. Slopes are 4 to 15 percent. Mean annual precipitation is about 300 mm and annual air temperature is about 3.9 degrees C.

TAXONOMIC CLASS: Loamy, mixed, superactive, frigid Lithic Haplustalfs

TYPICAL PEDON: Joegale loam, in rangeland (colors are for dry soil unless otherwise noted).

A--0 to 6 cm; brown (10YR 4/3) loam, very dark grayish brown (10YR 3/2), moist; weak fine granular structure; very friable, soft, slightly sticky, slightly plastic; many fine and common medium roots; many very fine dendritic tubular pores; 5 percent gravel; slightly effervescent; slightly alkaline (pH 7.8); clear smooth boundary. (3 to 7 cm thick)

Btk1--6 to 24 cm; dark yellowish brown (10YR 4/6) loam, dark yellowish brown (10YR 3/4), moist; moderate medium subangular blocky structure; friable, slightly hard, moderately sticky, moderately plastic; common fine and many medium roots; few fine dendritic tubular pores; 6 percent faint clay films on all faces of peds; 1 percent fine irregular carbonate nodules in matrix; 5 percent gravel; strongly effervescent; moderately alkaline (pH 8.0); clear wavy boundary. (12 to 36 cm thick)

Btk2--24 to 45 cm; brownish yellow (10YR 6/6) clay loam, yellowish brown (10YR 5/4), moist; weak medium subangular blocky structure; firm, moderately hard, moderately sticky, moderately plastic; few fine roots; few fine dendritic tubular pores; 6 percent faint clay films on all faces of peds; 5 percent fine irregular carbonate nodules in matrix; 5 percentgravel; violently effervescent; moderately alkaline (pH 8.4); clear wavy boundary. (10 to 23 cm thick)

R--45; calcareous sandstone bedrock.

Joebas (CO) - does not have a calcic horizon
Lajuita (NM) - does not have a calcic horizon

GEOGRAPHIC SETTING:
Landform - shoulders and summits of hillslopes
Elevation - 1,925 to 2,310 meters
Slope - 4 to 15 percent
Parent Material - slope alluvium over residuum weathered from calcareous sandstone and limestone
Climate - long, cold winters; cool, moist springs; short, cool summers.
Mean annual precipitation - 250 to 350 mm
Mean annual air temperature - 2.2 to 5.7 degrees C.

GEOGRAPHICALLY ASSOCIATED SOILS: None listed.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained, Ksat in particle-size control section 1.5-15.0 um/sec.

USE AND VEGETATION: Joegale soils are primarily used for rangeland. The potential native vegetation is mainly Wyoming big sagebrush, bottlebrush squirreltail, Sandberg bluegrass, Indian ricegrass, and other forbs and grasses.

DISTRIBUTION AND EXTENT: Joegale soils are of small extent in southwestern Wyoming. MLRA 46.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana

SERIES PROPOSED: Lincoln County, Wyoming, 2015. The series name is derived from a local landmark.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - 0 to 6 cm (A horizon)
Argillic horizon- 6 to 45 cm (Btk1, Btk2 horizons)
Calcic horizon - 24 to 45 cm (Btk2 horizon)
Lithic contact - at 45 cm (R horizon)
Particle-size control section - from 6 to 45 cm (Btk1, Btk2 horizons).

Joegale soils have a frigid temperature regime and an ustic moisture regime bordering on aridic.
