LOCATION JANA UTEstablished Series
TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, mesic, shallow Typic Haploxerepts
TYPICAL PEDON: Jana very gravelly loam, on a southwest facing, convex, 35 percent slope in juniper woodland at an elevation of 6,100 feet. (Colors are for dry soil unless otherwise noted.) When described on September 24, 1996, the soil was dry throughout.
The surface is covered by 40 percent gravel and 10 percent cobble.
A1--0 to 1 inches; dark brown (7.5YR 3/3) very gravelly loam; brown (7.5YR 5/3) dry; weak fine granular structure; soft, friable, slightly sticky and slightly plastic; 30 percent gravel and 10 percent cobbles; strongly effervescent; moderately alkaline (pH 8.2); clear smooth boundary (1 to 4 inches thick).
A2--1 to 6 inches; brown (7.5YR 4/3) very gravelly loam; light brown (7.5YR 6/3) dry; weak fine subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; 30 percent gravel, and 10 percent cobbles; strongly effervescent; moderately alkaline (pH 8.2); clear wavy boundary (3 to 7 inches thick).
Bw--6 to 12 inches; reddish brown (5YR 5/4) extremely cobbly loam; light reddish brown (5YR 6/4) dry; weak fine subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; 40 percent gravel and 20 percent cobbles; strongly effervescent; moderately alkaline (pH 8.4); abrupt irregular boundary (6 to 10 inches thick).
Cr--12 inches; fractured soft sandstone bedrock

Parent material: Slope alluvium, colluvium and residuum derived from conglomerate, sandstone and shale.
Landform: Mountain slopes
Slopes: 30 to 70 percent
Elevation: 5,600 to 7,400 feet
Mean annual air temperature: 45 to 48 degrees F.
Mean annual precipitation: 14 to 16 inches.

Driest months: July through September
Frost-free period: 100 to 120 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Dastrup,
Fewkes and
Richsum.

Fewkes: Very deep soils on mountain slopes
Richsum: Deep soils on mountain slopes
DRAINAGE AND PERMEABILITY: Well drained, medium to high runoff, moderate to moderately rapid permeability.
USE AND VEGETATION: Use is livestock grazing. Vegetation is Utah juniper, wheatgrass, bluegrass, and cliffrose. In Utah this series is in a Upland Shallow Loam (Utah Juniper) woodland site.
