BOOTH SERIES
The Booth series consists of moderately deep, well drained soils that formed in residuum and colluvium derived from tuff or basalt. Booth soils are on mountains, hills or plateaus. Slopes are 0 to 65 percent. The mean annual precipitation is about 380 mm and the mean annual temperature is about 6 degrees C.
TAXONOMIC CLASS: Fine, smectitic, frigid Vertic Palexerolls
TYPICAL PEDON: Booth very stony loam--rangeland. (Colors are for moist soil unless otherwise noted.)
A--0 to 10 cm; very dark brown (10YR 2/2) very stony loam, dark gray (10YR 4/1) dry; weak thin platy structure; hard, friable, slightly sticky and slightly plastic; many roots; many very fine pores; 20 percent gravel and 20 percent cobbles and stones; slightly acid (pH 6.2); clear smooth boundary. (3 to 30 cm thick)
2Bt1--10 to 30 cm; very dark brown (10YR 2/2) clay, dark grayish brown (10YR 4/2) dry; moderate medium and coarse prismatic structure; very hard, very firm, very sticky and very plastic; common roots; few very fine tubular pores; nearly continuous stress cutans on peds; slightly acid (pH 6.4); clear smooth boundary. (15 to 30 cm thick)
2Bt2--,30 to 61 cm; dark brown (10YR 3/3) clay, grayish brown (10YR 5/2) dry; brown (10YR 4/3) rubbed; strong coarse prismatic structure; very hard, very firm, very sticky and very plastic; few roots; few very fine tubular pores; continuous stress cutans on peds; neutral (pH 6.6); abrupt smooth boundary. (25 to 50 cm thick)

Campcreek , Crowcamp, Jesh, Joenchris, Kidnapspspring, Lacrol, Longburn, Meaufun, Tippett, and Warpaint soils are more than 100 cm to bedrock . Carryback soils have an aridic soil moisture regime bordering xeric. Golars, Haskins, Peavinet soils have a mollic epipedon thicker than 40 cm thick. Tippett and Zumwalt soils have secondary carbonates,
GEOGRAPHIC SETTING: Booth soils are on mountains, hills, or plateaus at elevations of 1,220 to 2,075 meters. Slopes range from 0 to 65 percent. The soils formed in residuum and coluvium derived from tuff. The climate is characterized by hot dry summers and cold wet winters. The mean annual precipitation is 300 to 460 mm. The mean July temperature is 16 to 18 degrees C, mean January temperature is about -4 to -2 degrees C, mean annual temperature is 4 to 7 degrees C. The frost-free period is 50 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Nuss and
Royst soils. Nuss soils are loamy, 25 to 50 cm deep to bedrock. Royst soils have a mollic epipedon over 50 cm thick and are clayey-skeletal. Nuss and Royst soils are on hills, plateaus, or structural benches.
DRAINAGE AND PERMEABILITY: Well drained; slow permeability; moderately low saturated hydraulic conductivity.
USE AND VEGETATION: Used for livestock grazing, wildlife, and recreation. Native vegetation is low sagebrush, bluebunch wheatgrass, and Idaho fescue.
DISTRIBUTION AND EXTENT: South-central Oregon and northern California (MLRA 21). The series is extensive.
