TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, mesic, shallow Typic Durixerolls
TYPICAL PEDON: Appleshall gravelly clay loam--rangeland. On a 2 percent slope at an elevation of 3,330 feet. (The profile was dry when described on July 28, 1980. Colors are for air-dry soil unless otherwise stated.)
A--0 to 6 inches; grayish brown (10YR 5/2) gravelly clay loam, very dark grayish brown (10YR 3/2) moist; moderate fine and coarse granular structure; hard, friable, slightly sticky and slightly plastic; many very fine roots; many very fine irregular pores; about 35 percent pebbles neutral (pH 7.0); clear smooth boundary. (2 to 8 inches thick)
Bt--6 to 12 inches; grayish brown (10YR 5/2) very gravelly clay loam, dark brown (10YR 3/3) moist; moderate fine subangular blocky structure; hard, firm, sticky and plastic; common very fine roots; common very fine irregular pores; about 45 percent pebbles; few thin clay films on faces of peds; neutral (pH 7.0); abrupt wavy boundary. (6 to 14 inches thick)
Bqm--12 to 13 inches; thin duripan with continuous laminar surface; abrupt wavy boundary. (1/8 to 1 inch thick)
2C--13 to 60 inches; multicolored extremely gravelly sand; massive; slightly hard, very friable; mildly alkaline (pH 7.6)

COMPETING SERIES: At present there are none in the same family. A soil in a closely related family is the Patelzick soil. Patelzick soils have a mean annual soil temperature of less than 47 degrees F.
GEOGRAPHIC SETTING: Appleshall soils are on terraces in an intermound position. Slopes range from 2 to 10 percent. Elevation ranges from 2,500 to 3,500 feet. The soil formed in old mixed alluvium from basalt, granite and some metamorphic rock. Climate is mesic with an annual precipitation of 16 to 25 inches, most of which falls as snow in winter. The average annual air temperature is about 48 to 52 degrees F. The frost-free season is 110 to 130 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are Appledellia, Bakeoven, Deshler, Gem. Longrell, Meland, Midvale, Newell, Reywat and Riggins. Appledellia soils are 20 to 40 inches deep to a duripan. All other soils lack a duripan. Bakeoven soils are very shallow to basalt. Deshler soils are moderately deep to tuff. Gem and Meland are moderately deep to basalt. Longrell, Midvale and Newell are deep. Reywat and Riggins are shallow to basalt.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; slow permeability.
USE AND VEGETATION: Used mainly for range. Potential native vegetation is stiff sagebrush and Sandberg bluegrass.
DISTRIBUTION AND EXTENT: Southwestern Idaho. The series is not extensive.
