COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING: Goosebury soils are on outwash fans and fan terraces. These soils formed in alluvium dominantly from limestone. Slopes are 2 to 35 percent. Elevations are 6,300 to 8,000 feet. The climate is cold and moist in winter and spring, and cool and dry in the summer. The average annual precipitation is 8 to 13 inches. The average annual temperature is 35 to 40 degrees F. and the frost-free period is 30 to 60 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dawtonia, Sactus, Simeroi and Snowslide soils. Dawtonia soils are on mountains and have an argillic horizon. Sactus soils are on mountains and are very shallow to bedrock. Simeroi and Snowslide soils are on outwash fans and fan terraces. Simeroi soils have carbonatic mineralogy. Snowslide soils have an average summer soil temperature of 59 to 63 degrees F.
DRAINAGE AND PERMEABILITY: Well drained. Slow runoff; moderate permeability in the upper part and very rapid or moderately rapid in the lower part.
USE AND VEGETATION: Rangeland. Vegetation is mainly black sagebrush, needleandthread, and Indian ricegrass.
DISTRIBUTION AND EXTENT: East-central Idaho. These soils are not extensive.
