TICANOT SERIES
The Ticanot series consists of shallow, well drained soils that formed in colluvium over residuum weathered from basalt or sedimentary rock. These soils are on mountain slopes. Slopes are 3 to 65 percent. Mean annual precipitation is about 600 cm, and mean annual air temperature is about 4.4 degrees C.
TAXONOMIC CLASS: Clayey-skeletal, smectitic Lithic Argicryolls
TYPICAL PEDON: Ticanot very cobbly loam in rangeland.(Colors are for dry soils unless otherwise noted).
A--0 to 13 cm; 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.
AB--13 to 28 cm; 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.
Bt--28 to 38 cm; 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 on surfaces along pores; neutral (pH 6.6) gradual smooth boundary.
R--38 cm; basalt with clay films in the cracks.

COMPETING SERIES:
Tica (ID)--soils are intermittently moist in some part of the moisture control section for 10 to 20 cumulative days between July and September in a 350 to 575 mm precipitation zone.
GEOGRAPHIC SETTING:
Landform--mountain slopes
Elevation--1,160 to 2,500 meters
Slope--3 to 65 percent
Parent material-- colluvium over residuum weathered from basalt or sedimentary rock
Climate--long, cold winters; cool, moist springs; short, cool summers
Mean annual precipitation--575 mm to 1,000 mm[NK2.1]
ean annual air temperature--2.2 to 7.0 degrees C
Frost-free period--30 to 75 days
GEOGRAPHICALLY ASSOCIATED SOILS: None listed.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained, 0.5 to 15.0 um/sec.
USE AND VEGETATION: Ticanot soils are primarily used for grazing, recreation, and wildlife habitat. The potential native vegetation is ponderosa pine, Idaho Fescue, bluebunch wheatgrass, elk sedge, arrowleaf balsamroot, mountain snowberry, and mountain big sagebrush.
DISTRIBUTION AND EXTENT: Ticanot soils are of moderate extent in central and southeastern Idaho; MLRA 43B.
