Bg1--13 to 19 inches; dark gray (10YR 4/1) clay loam, very dark gray (10YR 3/1) moist; few fine prominent brown (7.5YR 5/4) moist mottles; strong medium angular blocky structure; hard, firm, sticky and plastic; common fine roots; common fine tubular pores; neutral (pH 6.9); gradual smooth boundary. (4 to 9 inches thick)
Bg2--19 to 24 inches; gray (10YR 5/1) clay, very dark grayish brown (10YR 3/2) moist; common fine prominent dark brown (7.5YR 4/4) moist mottles; strong medium angular blocky structure; very hard, very firm, very sticky and very plastic; few fine roots; few fine tubular pores; neutral (pH 6.6); clear smooth boundary. (4 to 9 inches thick)
Cg--24 to 62 inches; gray (2.5Y 5/1) clay, dark gray (2.5Y 4/1) moist; massive; very hard, very firm, very sticky and very plastic, neutral (pH 6.6). (30 to 41 inches thick)

COMPETING SERIES: These are the Crooked Creek, and Dovray soils. Crooked Creek soils lack B horizons and occur in a 16 to 22 inch precipitation zone. Dovray soils occur in an 18 to 22 inch precipitation zone, and have clay texture in the upper part of the control section.
GEOGRAPHIC SETTING: Hutton soils are on floodplains and in depressions. Slopes range from 0 to 4 percent. Elevation ranges from 4,700 to 5,800 feet. The soil formed in alluvium from mixed sources. Average annual precipitation is 12 to 16 inches, most of which falls as snow and early spring rain. The average annual air temperature is about 41 to 46 degrees F. The frost-free season is 50 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bringmee, Bruneel, Carey Lake, Little Wood, and Marshdale series. Bringmee soils are well drained. Bruneel soils are in a coarse loamy over sandy or sandy-skeletal family. Carey Lake soils are well drained and are in a fine-loamy family. Little Wood soils are well drained and are in a loamy-skeletal family. Marshdale soils are poorly drained and are in a fine-loamy family. Bringmee, Carey Lake, and Little Wood soils are on fan terraces and stream terraces. Bruneel and Marshdale are on similar landscapes to the Hutton series.
DRAINAGE AND PERMEABILITY: Poorly drained; runoff is ponded to slow; permeability is very slow.
USE AND VEGETATION: Mainly used for limited cropland and pasture. Natural vegetation is wet meadow grasses, shrubby cinquefoil, basin wildrye, and foxtail barley.
DISTRIBUTION AND EXTENT: The series is inextensive in south-central Idaho.
