BAk--5 to 10 inches; pale brown (10YR 6/3) gravelly loam, dark brown (10YR 4/3) moist; weak medium subangular blocky structure; slightly hard, very friable, slightly sticky and slightly plastic; many fine and very fine, and common medium tubular pores; matrix strongly effervescent (35 percent calcium carbonate equivalent); common lime coats 1 to 2 mm thick on undersides of rock fragments; 35 percent limestone gravel; slightly alkaline (pH 7.7); clear smooth boundary. (4 to 6 inches thick)
Bk1--10 to 26 inches; light gray (10YR 7/2) very gravelly loam, dark brown (10YR 4/3) moist; massive; slightly hard, very friable, slightly sticky and slightly plastic; common very fine, and fine roots; few very fine tubular pores; matrix violently effervescent (45 percent calcium carbonate equivalent); common lime coats 1 to 2 mm thick on undersides of rock fragments; 40 percent limestone gravel; moderately alkaline (pH 8.0); clear smooth boundary. (14 to 16 inches thick)
Bk2--26 to 39 inches; light gray (10YR 7/2) very gravelly loam, brown (10YR 5/3) moist; massive; slightly hard, very friable, slightly sticky and slightly plastic; common very fine and fine roots; few very fine tubular pores; matrix strongly effervescent (40 percent calcium carbonate equivalent); common lime coats 1 to 2 mm thick on undersides of rock fragments; 45 percent limestone gravel; moderately alkaline (pH 8.4); clear wavy boundary. (13 to 19 inches thick)
Bkq--39 to 56 inches; light gray (10YR 7/2) very gravelly loam, brown (10YR 5/3) moist; massive; slightly hard, very friable, slightly sticky and slightly plastic; few very fine roots; some root matting in gravel; matrix strongly effervescent (40 percent calcium carbonate equivalent); lime coats and few silica pendants 1 to 2 mm thick on undersides of coarse fragments; 35 percent limestone gravel; moderately alkaline (pH 8.4).
TYPE LOCATION: Butte County, Idaho; on Beaverland Pass, 5 miles east of Moore, Idaho; about 500 feet east and 100 feet north of the southwest corner of section 19, T. 5 N., R. 27 E. Latitude - 43 degrees, 44 minutes, 7 seconds N.; Longitude - 113 degrees, 17 minutes, 25 seconds W.
RANGE IN CHARACTERISTICS:
Profile:
Average annual soil temperature - 40 to 44 degrees F.
Reaction - slightly to moderately alkaline
Particle-size control section:
Clay - 10 to 18 percent
Calcium carbonate equivalent - 40 to 50 percent including rock fragments less than 20 mm
Rock fragment content - 35 to 50 percent
A horizon:
Value - 5 or 6 dry and 3 or 4 moist
BAk horizon:
Texture - GR-SIL, GR-L or GRV-L
Bk horizons:
Value - 4 or 5 moist
Texture - GRV-SIL or GRV-L
Rock fragments - 35 to 50 percent

COMPETING SERIES: These are the Adek, Dryadine, and Whitore series. Adek soils average more than 50 percent rock fragments in the particle-size control section and have silica coats or pendants on rock fragments above 30 inches. Dryadine soils have bedrock at 21 to 40 inches. Whitore soils have an 0 horizon, 16 to 26 inches of annual precipitation and 25 to 35 percent clay in the particle-size control section.
GEOGRAPHIC SETTING: Bealand soils are on north-facing limestone mountainsides, ridgetops and foothills. Elevations range from 6,000 and 8,500 feet. They formed in slope alluvium and colluvium dominantly from limestone. Slopes range from 20 to 70 percent. The average annual precipitation is 13 to 18 inches, most of which is in the form of snow. The average annual air temperature is 38 to 42 degrees F. The frost-free season is 40 to 55 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Fritz (T), Jimbee (T), Meegero and the Zeale series. Fritz (T), Jimbee (T), Meegero and Zeale soils all have mollic surface horizons. Jimbee soils are also shallow to bedrock.
DRAINAGE AND PERMEABILITY: Well drained; rapid to very rapid runoff; moderate permeability.
USE AND VEGETATION: Bealand soils are used primarily for rangeland and wildlife habitat. Vegetation is mainly low sagebrush and bluebunch wheatgrass.
DISTRIBUTION AND EXTENT: The series is of small extent on limestone mountains in southeastern Idaho.
