BAILEY SERIES

The Bailey series consists of very deep, well drained soils formed in colluvium derived from rhyolite and tuff with loess influence. Bailey soils are on canyon walls and have slopes of 4 to 80 percent. The mean annual precipitation is about 430 mm and the mean annual air temperature is about 7.5 degrees C.

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, frigid Calcic Haploxerolls

TYPICAL PEDON: Bailey very gravelly loam on a side slope of a canyon with 65 percent slope at an elevation of 1,731 meters. (Colors are for dry soil unless otherwise noted.) The surface is covered by 30 percent gravel, 15 percent cobbles and 5 percent boulders.

A--0 to 26 cm; dark grayish brown (10YR 4/2) very gravelly loam, very dark grayish brown (10YR 3/2) moist; weak fine subangular blocky structure parting to weak very fine granular; soft, very friable, slightly sticky and slightly plastic; common very fine, fine and medium roots; many very fine irregular pores; 40 percent gravel; 10 percent cobbles; slightly alkaline (pH 7.4); clear wavy boundary. (25 to 50 cm thick)

Bw--26 to 60 cm; yellowish brown (10YR 5/4) extremely gravelly loam, dark yellowish brown (10YR 3/4) moist; weak fine subangular blocky structure parting to weak very fine granular; soft, very friable, slightly sticky and slightly plastic; common very fine and fine and few medium roots; many very fine irregular and common very fine tubular pores; calcium carbonate coats on bottoms of rock fragments; 50 percent gravel and 10 percent cobbles; slightly alkaline (pH 7.4); clear wavy boundary. (15 to 80 cm thick)

Bk1--60 to 120 cm; light gray (10YR 7/2) extremely gravelly fine sandy loam, brown (10YR 4/3) moist; weak medium subangular blocky structure; slightly hard, very friable, nonsticky and nonplastic; few very fine, fine and medium roots; common very fine tubular pores; many calcium carbonate coats on rock fragments; many calcium carbonate masses; 40 percent gravel, 5 percent cobbles, 10 percent flagstones, and 5 percent stones; strongly effervescent (15 percent calcium carbonate equivalent); moderately alkaline (pH 8.0); clear wavy boundary.

Bk2--120 to 152 cm; pale yellow (2.5Y 7/3) extremely gravelly fine sandy loam, brown (10YR 5/3) moist; weak medium subangular blocky structure; soft, very friable, nonsticky and nonplastic; few very fine roots; common very fine tubular pores; common calcium carbonate threads; 55 percent gravel, 10 percent cobbles, 15 percent flagstones, and 5 percent stones; slightly effervescent (6 percent calcium carbonate equivalent); slightly alkaline (pH 7.8); clear wavy boundary. (Combined thickness of the Bk horizons is 50 to greater than 92 cm)

COMPETING SERIES: These are the Conneridge, Ireland, Jebo, Pedleford, Tuckerdown Hondoho, Dagan, Buist, Cooley, and Niarada soil series. Conneridge, Ireland, Jebo, Pedleford soils are moderately deep. Hondaho and Tuckerdowns have greater than 18 percent clay in the particle size control section. Dagan soils have hues redder than 7.5YR. Buist has less than 50 percent rock fragments and no flagstones in the particle size control section. Cooley has less than 30 percent very fine and fine sands in the particle size control section. Niarada has a cambic horizon free of calcium carbonates and does not have flagstones in the particle size control section.

GEOGRAPHIC SETTING:
