CUBLEE SERIES

The Cublee series consists of very deep, well drained soils that formed in alluvium derived from igneous, metamorphic and limestone rock. The Cublee soils are on lake plains. Slopes range from 0 to 4 percent. The mean annual precipitation is about 100 millimeters (4 inches) and the mean annual air temperature is about 18 degrees C (64 degrees F).

TAXONOMIC CLASS: Fine-silty, mixed, superactive, thermic Leptic Haplogypsids

TYPICAL PEDON: Cublee silty clay, on a north facing (0 degree), 2 percent slope at an elevation of 780 meters (2560 feet). When described on 3/12/2009 the soil was dry throughout. Colors are for dry soils unless otherwise noted.

(0 to 7 centimeters thick)

(4 to 20 centimeters)

By1--9 to 30 centimeters (4 to 12 inches); light yellowish brown (10YR 6/4) silt loam, yellowish brown (10YR 5/4) moist; moderate coarse prismatic structure; very hard, firm, moderately sticky and moderately plastic; common fine and common medium throughout roots; common fine and many very fine tubular pores; 10 percent fine distinct, spherical, white (10YR 8/1), gypsum masses with sharp boundaries in matrix and 2 percent fine, distinct, irregular weakly- cemented, white (10YR 8/1), gypsum crystals with sharp boundaries in matrix; strongly effervescent; moderately alkaline (pH 8.4); clear smooth boundary.

By2--30 to 48 centimeters (12 to 19 inches); light yellowish brown (10YR 6/4) silt loam, yellowish brown (10YR 5/4) moist; weak medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; common fine throughout roots; common fine tubular and many very fine tubular pores; 5 percent fine, distinct, spherical, white (10YR 8/1), gypsum masses with clear boundaries in matrix and 2 percent fine, distinct, spherical, weakly-cemented, white (10YR 8/1), gypsum crystals with sharp boundaries in matrix; strongly effervescent; moderately alkaline (pH 8.4); clear wavy boundary.

By3--48 to 150 centimeters (19 to 59 inches); light yellowish brown (10YR 6/4) silt loam, yellowish brown (10YR 5/6) moist; massive; slightly hard, friable, slightly sticky and slightly plastic; 1 percent fine, distinct, spherical, white (10YR 8/1), gypsum masses with clear boundaries in matrix; violently effervescent; strongly alkaline (pH 8.6). (Combined thickness of the By horizons is 125 to 160 centimeters.)

COMPETING SERIES: This is the Aerobee series. The Aerobee soils have a mean annual soil temperature of 17 to 19 degrees C (62 to 66 degrees F) and 15 to 35 percent by weight gypsum in the particle-size control section.

GEOGRAPHIC SETTING: The Cublee soils are on lake plains. Slopes range from 0 to 4 percent. These soils formed in alluvium derived from igneous, metamorphic and limestone rock. Elevation is 775 to 790 meters (2550 to 2590 feet). The climate is arid with hot, dry summers and cool, moist winters. The mean annual precipitation is 75 to 125 millimeters (3 to 5 inches) and the mean annual air temperature is 17 to 20 degrees C (63 to 68 degrees F). The frost free season is 240 to 300 days

GEOGRAPHICALLY ASSOCIATED SOILS: This is the Haymont soils. Haymont soils are on lake plains and have a coarse-loamy particle-size control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; low or medium runoff; moderately low saturated hydraulic conductivity.

USE AND VEGETATION: These soils are used for rangeland and wildlife habitat. The present vegetation is mainly Mojave seablite, Torrey's saltbush and honey mesquite.

DISTRIBUTION AND EXTENT: Mojave Desert of southeastern California, U.S.A.; MLRA 30. These soils are not extensive.
