TYPE LOCATION: Mohave County, Arizona; latitude of 34 degrees, 31 minutes, 41 seconds north and a longitude of 113 degrees, 24 minutes, 27 seconds west; 1,600 feet south and 50 feet east of the northwest corner of section 27, T. 14 N., R. 11 W.

COMPETING SERIES: These are the Bylas (T) (AZ), Crosgrain (NV), Gotchell (AZ), Greyeagle (CA), Longjim (NV), Marsite (CA), and Tumarion (AZ) series. Bylas soils are shallow to limestone bedrock, have secondary accumulations of calcium carbonate, and are dominated by calcrete flagstones. Crosgrain, Gotchell, Greyeagle, Longjim, Marsite, and Tumarion soils precipitation is greatest in the winter with a lesser secondary peak in summer, typical of the Mojave Desert (MLRA 30) and are moist for less than 20 cumulative days during July-September. In addition Crossgrain and Greyeagle soils do not have bedrock at depths less than 20 inches; Gotchell soils are shallow to fanglomerate bedrock; Longjim soils do not have bedrock within 20 inches and have less than 10 percent clay; and Marsite soils have less than 12 percent clay.
GEOGRAPHIC SETTING: Cline soils are on mesas. Slopes range from 2 to 15 percent. These soils formed in alluvium from volcanic rock. Elevations range from 2,400 to 4,900 feet. The mean annual precipitation is 7 to 12 inches. The mean annual air temperature is 59 to 70 degrees F. The frost-free period is about 200 to 250 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Akela and Stagecoach soils. Akela and Stagecoach soils do not have a duripan. Stagecoach soils are very deep.
DRAINAGE AND PERMEABILITY: Well drained; medium to very high runoff; moderate permeability.
USE AND VEGETATION: Used for livestock grazing and wildlife habitat. Vegetation includes big galleta, bush muhly, black grama, creosotebush, little leaf paloverde and range ratany.
DISTRIBUTION AND EXTENT: Northwestern Arizona. This series is of moderate extent. MLRA is 40. The name is from a local ranch.
