(7 to 19 inches thick)
Bk--34 to 36 inches; light gray (10YR 7/2) very fine sandy loam, grayish brown (10YR 5/2) moist; moderate medium and coarse subangular blocky structure; soft, friable, slightly plastic; violently effervescent; many soft accumulations of calcium carbonate; moderately alkaline (pH 8.0); abrupt irregular boundary. (2 to 8 inches thick)
2R--36 inches; unweathered, vesicular basalt.

COMPETING SERIES: This is the Jipper series. Jipper soils are deep or very deep.
GEOGRAPHIC SETTING: Stipe soils are on basalt plains. They formed in wind blown material from mixed sources. Slopes range from 1 to 8 percent. Elevation ranges from 5,000 to 5,800 feet. Average annual temperature is 37 to 42 degrees F and the average precipitation is 13 to 16 inches, including 3 to 6 feet of snowfall. Average summer temperature ranges from 61 to 63 degrees F. The frost-free season ranges from 80 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Blacknoll(T), Jipper(T), Katseanes(T), Nayrib(T), Pinebutte(T), Snowshoe(T), Vadnais(T), and Wolverine soils. Blacknoll soils lack a mollic epipedon. Jipper soils are deep to basalt. Katseanes soils are shallow and have an argillic horizon. Nayrib soils are very shallow and are on pressure ridges of the basalt plain. Pinebutte soils have an argillic horizon. Vadnais soils have an argillic horizon. Snowshoe soils are coarse textured windblown deposits over finer textured material and are more than 60 inches deep. Wolverine soils are on stabilized dunes and lack a cambic horizon. The Katseanes and Pinebutte soils are in areas of higher elevation with more precipitation. Snowshoe and Wolverine soils are on stabilized sandunes.
DRAINAGE AND PERMEABILITY: Well drained; moderate permeability.
USE AND VEGETATION: Rangeland, cropland, and wildlife habitat. Principal native vegetation is mountain big sagebrush, antelope bitterbrush, and bunchgrasses.
DISTRIBUTION AND EXTENT: Stipe soils are inextensive in eastern Idaho.
