COMPETING SERIES: This is the Dinkey series. Dinkey soils have muck surface layers.
GEOGRAPHIC SETTING: Bane soils are on alluvial fans at the mouth of steep canyons. Slopes range from 2 to 8 percent. They formed in recent deposits of granitic alluvium. Elevations range from 1,500 to 2,700 feet. The climate is subhumid with cold, wet winters and warm, dry summers. The average annual air temperature ranges from 42 to 44 degrees F., and the average annual precipitation is 25 to 30 inches. The average frost-free period is 90 to 110 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Farnhamton, Ritz and Schnoorson soils. Farnhamton soils are on natural levees and have coarse-silty control sections and are moderately well drained. Ritz soils are on low stream terraces and plane to convex areas of flood plains, and have coarse-silty control sections and are poorly drained. Schnoorson soils are on swales and concave areas on flood plains and have fine-silty control sections and are poorly drained.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; very slow runoff; rapid permeability.
USE AND VEGETATION: Woodland, wildlife habitat, and recreation. Some areas are used for homesites. Some small areas are cultivated and are in grass pasture. Natural vegetation is mainly western redcedar, grand fir, western white pine, western larch, Douglas-fir, and lodgepole pine, with an understory of rocky mountain maple, sweet scented bedstraw, queencup beadlily, common princes pine, western rattlesnake plaintain, longtube twinflower, and darkwoods violet.
DISTRIBUTION AND EXTENT: Northern Idaho, and possibly northeastern Washington, and northwestern Montana. The series is not extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana
SERIES ESTABLISHED: Boundary County, Idaho, 1974.
REMARKS: Classification change from Typic Cryorthents to Typic Xerofluvents in 1994. Changed to Typic Udifluvents in 2000 because vegetation indicates a udic moisture regime.
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the mineral soil surface to 6 inches (A horizon)
Buried A horizon - the zone from 39 to 43 inches (3Ab horizon)
Particle-size control section - the zone from 11 to 41 inches (part of the C1, the 2C2, and part of the 3Ab horizon)
