TAXONOMIC CLASS: Loamy-skeletal, carbonatic, frigid Lithic Haplocalcids
TYPICAL PEDON: Inel stony silt loam - on a 20 percent west facing slope at an elevation of 5,850 feet in rangeland. The vegetation is shadscale and Indian ricegrass. When described on July 28, 1986, the soil was slightly moist throughout. (Color is for dry soil unless otherwise noted.)

(2 to 4 inches thick)
Bw--3 to 9 inches; pale brown (10YR 6/3) gravelly silt loam, brown (10YR 4/3) moist; weak fine subangular blocky structure; slightly hard, very friable, nonsticky and slightly plastic; many very fine, fine and few medium roots; common very fine tubular pores; 10 percent gravel, 5 percent cobbles and 3 percent stones; strongly effervescent (35 percent calcium carbonate equivalent); moderately alkaline (pH 8.0); clear smooth boundary. (4 to 8 inches thick)
Bkq1--9 to 13 inches; very pale brown (10YR 7/3) very gravelly loam, brown (10YR 5/3) moist; weak fine subangular blocky structure; slightly hard, very friable, nonsticky and slightly plastic; common very fine, fine and medium roots; common very fine tubular pores; 15 percent gravel, 15 percent cobbles and 5 percent stones; matrix violently effervescent (40 percent calcium carbonate equivalent); common lime and silica coats 1 to 2 mm thick on undersides of rock fragments; moderately alkaline (pH 8.3); gradual wavy boundary. (4 to 6 inches thick)
Bkq2--13 to 19 inches; very pale brown (10YR 7/3) very cobbly loam, brown (10YR 4/3) moist; weak fine subangular blocky structure; slightly hard, very friable, nonsticky and slightly plastic; common very fine, fine and medium roots; common very fine tubular pores; 15 percent gravel, 20 percent cobbles, and 5 percent stones; violently effervescent (40 percent calcium carbonate equivalent); common lime and silica coats 1 to 2 mm thick on undersides of rock fragments; moderately alkaline (pH 8.2); gradual wavy boundary. (4 to 6 inches thick)
R--19 inches; hard limestone.

COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: Inel soils occur on limestone ridgetops and sideslopes of foothills and mountains. They formed in residuum and colluvium. Slopes are 10 to 55 percent. Elevations range from 4,500 to 6,500 feet. The precipitation ranges from 7 to 8 inches, most of which is in the form of snow. The average annual air temperature is 42 to 45 degrees F. The frost free season is 70 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ike, Simeroi, Slide, and McCaleb (T) soils. Ike soils occur on north slopes and higher elevations. Simeroi, Slide, and McCaleb soils are very deep soils on fan terraces. Slide soils are also on foothills.
DRAINAGE AND PERMEABILITY: Well drained; rapid runoff; moderate permeability.
USE AND VEGETATION: Used primarily for rangeland and wildlife habitat. Vegetation is mainly shadscale and Indian ricegrass.
DISTRIBUTION AND EXTENT: Southcentral Idaho. These soils are not extensive.
