COMPETING SERIES: These are the Anniecreek, Bigbutte, Brownsbowl, Cadero, Greengrove, Hallet, Medrick, and Pannfield series.
Anniecreek soils have depth to aquic conditions of 50 to 89 cm, have dominantly ashy sandy texture, and have a udic moisture regime. Bigbutte soils are moderately deep to paralithic contacts and have an ustic moisture regime. Brownsbowl soils average 20 to 35 percent rock fragments in the particle-size control section, do not have fluvial stratification and buried A horizons, and do not have endosaturation and aquic conditions within the series control section. Cadero soils are moderately deep to paralithic contacts.Greengrove soils intermittently moist in the upper part for 10 to 20 days cumulative due to convection storms between July and September. Hallet soils have aquic conditions at 50 to 100 cm. Medrick and Pannfield soils have a ustic soil moisture regime.

GEOGRAPHIC SETTING: Bodiecreek soils are on low stream terraces. They formed in alluvium derived from mixed metamorphic and igneous rocks and volcanic ash. The probable sources of the volcanic ash are the Mono Craters and Long Valley Caldera in eastern California. Slopes are 0 to 4 percent. Elevations range from 2,286 to 2,438 meters. The climate is semiarid with cold, moist winters and cool, dry summers. The mean annual precipitation is 350 to 400 mm, the mean annual temperature is 6 to 7 degrees C., and the frost-free period is 30 to 60 days.

GEOGRAPHICALLY ASSOCIATED SOILS: This is the Longdrive soil. Longdrive soils have shallow aquic conditions and have mollic epipedons 50 to 100 cm thick.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained; very low surface runoff; moderately rapid permeability; high saturated hydraulic conductivity. Endosaturation is present with an apparent seasonal high water table between 100 and 150 cm (deep or very deep free water occurrence classes) from November through June. Cumulative annual duration class is Common or Persistent. Some areas of these soils are susceptible to occasional flooding for brief periods between December and September.

USE AND VEGETATION: Bodiecreek soils are used for livestock grazing, recreation, watershed, and wildlife habitat. The native vegetation is mainly silver sagebrush, rubber rabbitbrush, Douglas sedge, and Baltic rush.

DISTRIBUTION AND EXTENT: Eastern California, in the western part of the Great Basin. These soils are not extensive. MLRA 26.
