COMPETING SERIES: There are no other series listed in the same family. The closely related Bray series has an indurated duripan and does not have a calcic horizon above the duripan.
GEOGRAPHIC SETTING: Bailing soils are in concave positions on basalt plains and have slopes of 1 to 8 percent. Elevations range from 4,250 to 5,000 feet. The soil formed in loess and silty alluvium. The soils are in a semiarid climate with annual precipitation of 11 to 13 inches. The mean annual temperature is about 45 to 48 degrees F. The frost-free period is 85 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Darrah, Hamrub, Perla, and Ruckles. The Darrah soils are fine-silty and are very deep. Hamrub soils are fine-silty and have a Calcic horizon. Perla soils are moderately deep. Ruckles soils are 10 to 20 inches deep to basalt. These soils are also on basalt plains.
DRAINAGE AND PERMEABILITY: Well drained, medium runoff; very slow permeability.
USE AND VEGETATION: Used mainly for rangeland. Vegetation is three-tip sagebrush, Sandberg bluegrass, bluebunch wheatgrass, threeawn, balsamroot, mustard, and phlox.
DISTRIBUTION AND EXTENT: South central Idaho. The series is not extensive.
