LOCATION TICANOT IDEstablished Series
TAXONOMIC CLASS: Clayey-skeletal, smectitic Lithic Argicryolls
TYPICAL PEDON: Ticanot very cobbly loam - rangeland - on 5 percent slope at 3,880 feet elevation. Aspect is east. (Colors are for dry soils unless otherwise noted. When described on September 22, 1978 the soil was dry throughout.)
A--0 to 5 inches; brown (10YR 5/3) very cobbly loam, very dark grayish brown (10YR 3/2) moist; moderate very fine granular structure; slightly hard, friable, slightly sticky and slightly plastic; many fine and very fine roots; many very fine irregular pores; 40 percent cobbles; slightly acid (pH 6.4); clear wavy boundary. (5 to 8 inches thick)
AB--5 to 11 inches; brown (10YR 5/3) very cobbly clay loam, dark brown (10YR 3/3) moist; moderate fine subangular blocky structure parting to strong fine and very fine granular; slightly hard, friable, moderately sticky and moderately plastic; many very fine roots; many very fine irregular pores; 50 percent cobbles; neutral (pH 6.6); clear wavy boundary. (0 to 6 inches thick)
Bt--11 to 15 inches; brown (10YR 4/3) very cobbly clay, dark brown (7.5YR 3/2) moist; strong very fine subangular blocky structure; very hard, firm, very sticky and very plastic; many very fine roots; common very fine tubular pores; 50 percent cobbles; many prominent clay films on faces of peds and in pores; neutral (pH 6.6) gradual smooth boundary. (4 to 10 inches thick)
R--15 inches; basalt with clay films in the cracks.

COMPETING SERIES: This is the Tica series. Tica soils have are intermittently moist in some part of the moisture control section for 10 to 20 cumulative days between July and September in a 14 to 22 inch precipitation zone.
GEOGRAPHIC SETTING: Ticanot soils are on gently sloping to very steep hills and mountains at elevations of 3,800 to 6,000 feet. Slopes are 4 to 65 percent. The soils formed in residuum from basalt. The average annual precipitation is 22 to 26 inches and the average annual air temperature is 38 to 42 degrees F. The frost free season is 65 to 75 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Demast and Bluebell series. Demast soils are deep or very deep. Bluebell soils are moderately deep.
DRAINAGE AND PERMEABILITY: Well drained; medium to very rapid runoff; slow permeability.
USE AND VEGETATION: Used for rangeland, recreation, wildlife habitat, and watershed. Vegetation is scattered ponderosa pine with an understory of Idaho Fescue, bluebunch wheatgrass, elk sedge, arrowleaf balsamroot, snowberry, and mountain big sagebrush.
DISTRIBUTION AND EXTENT: West Central Idaho. The soil is moderately extensive.
