JOEMAY SERIES
The Joemay series consists of very deep, well drained soils that formed in alluvium derived from limestone. The Joemay soils are on fan remnanants on fan piedmont. Slopes range from 2 to 30 percent. The mean annual precipitation is about 125 millimeters and the mean annual air temperature is about 16 degrees C.

GEOGRAPHIC SETTING: The Joemay soils are on fan remnants. Slopes range from 2 to 30 percent. These soils formed in alluvium derived from limestone. Elevation is 920 to 1653 meters. The climate is arid with hot, dry summers and warm, moist winters. The mean annual precipitation is 127 to 178 millimeters and the mean annual air temperature is 13 to 17 degrees C. The frost free season is 200 to 260 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Alamoroad and
Threelakes soils. The Alamoroad soils have petronodic features at 50 to 100 centimeters and are on upper fan remnants. Threelakes soils do not have a calcic horizon and are on fan aprons.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained, moderately high saturated hydraulic conductivity, low to medium runoff.
USE AND VEGETATION: This soil is used for recreation and wildlife habitat. Vegetation is shadscale, creosotebush, white bursage and Spanish dagger.
