HUTCHLEY SERIES
The Hutchley series consists of shallow, well drained soils that are formed in residuum and colluvium derived from quartz latite and other related volcanic rocks and metasedimentary rocks. They are on cuestas, hills, mountainsides, plateaus and ridges. Slopes are 2 to 75 percent. The mean annual temperature is about 6 degrees C and the mean annual precipitation is about 380 mm.
TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, frigid Lithic Argixerolls

GEOGRAPHIC SETTING: Hutchley soils are on cuestas, hills, mountainsides, plateaus and ridges. Slopes are 2 to 75 percent. Elevation is 3,400 to 9,000 feet. The soils formed in alluvium, residuum, and colluvium derived from quartz latite, basalt, or related volcanic rocks and metasedimentary rocks with some loess influence. The mean annual precipitation is 305 to 508 mm, the mean annual air temperature is 3 to 7 degrees C., and the frost-free season is 30 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Heglar,
Rexburg,
Vitale, and
Watercanyon series. Heglar, Rexburg, and Watercanyon soils have coarse-silty control sections. Vitale soils are 50 to 100 cm deep. Heglar soils are on west-facing mountainsides. Rexburg soils are on north-facing mountainsides. Vitale soils are on south-facing mountainsides. Watercanyon soils are on similar positions as Hutchley soils.
DRAINAGE AND PERMEABILITY: Well drained; medium to very rapid runoff; moderately slow permeability.
USE AND VEGETATION: Hutchley soils are used for rangeland. The potential native vegetation is low sagebrush, bluebunch wheatgrass, and Sandberg bluegrass.
DISTRIBUTION AND EXTENT: Hutchley soils are of moderate extent.
