GOLDROSE SERIES

The Goldrose series consists of very deep, somewhat excessively drained soils that formed in alluvium from granitoid and/or gneissic rocks. The Goldrose soils are on alluvial fans. Slopes range from 4 to 8 percent. The mean annual precipitation is about 75 millimeters (3 inches) and the mean annual air temperature is about 24.5 degrees C (76 degrees F).

TAXONOMIC CLASS: Sandy, mixed, hyperthermic Typic Torriorthents

TYPICAL PEDON: Goldrose gravelly loamy fine sand, on a convex, 5 percent slope under desert shrubs at an elevation of 482 meters (1,560 feet). (Colors are for dry soil unless otherwise noted.) The surface is covered by approximately 50 percent fine gravel and 20 percent medium and coarse gravel.

A -- 0 to 3 centimeters (0 to 1 inch); brown (10YR 5/3) gravelly loamy fine sand, dark grayish brown (10YR 4/2) moist; weak medium subangular blocky structure; soft, very friable, nonsticky and nonplastic; few very fine and fine roots; 12 percent fine gravel and 3 percent medium and coarse gravel; very slightly effervescent; neutral (pH 7.3); clear wavy boundary. (2 to 6 centimeters thick)

Bw -- 3 to 14 centimeters (1 to 5.5 inches); brown (10YR 5/3) gravelly sand, brown (10YR 4/3) moist; weak fine subangular structure parting to single grain; soft, very friable, nonsticky and nonplastic; common very fine and fine roots; 15 percent fine gravel and 5 percent medium and coarse gravel; strongly effervescent; moderately alkaline (pH 8.1); clear wavy boundary. (0 to 92 centimeters thick)

C1 -- 14 to 54 centimeters (5.5 to 21 inches); pale brown (10YR 6/3) gravelly sand, brown (10YR 5/3) moist; single grain; loose, nonsticky and nonplastic; common very fine and fine and few medium roots; 20 percent fine gravel and 5 percent medium and coarse gravel; strongly effervescent; moderately alkaline (pH 8.1); gradual wavy boundary.

C2 -- 54 to 78 centimeters (21 to 31 inches); pale brown (10YR 6/3) gravelly coarse sand, brown (10YR 5/3) moist; single grain; loose, nonsticky and nonplastic; few very fine and fine roots; 25 percent fine gravel and 7 percent medium and coarse gravel; slightly effervescent; moderately alkaline (pH 8.1); gradual wavy boundary.

C3 -- 78 to 150 centimeters (31 to 60 inches); pale brown (10YR 6/3) very gravelly coarse sand, brown (10YR 5/3) moist; single grain; loose, nonsticky and nonplastic; 30 percent fine gravel, 12 percent medium and coarse gravel and 1 percent cobbles; slightly effervescent; moderately alkaline (pH 8.1). (Combined thickness of the C horizon is greater than 50 centimeters).

TYPE LOCATION: Riverside County, California; about 4.3 kilometers (2.7 miles) NNW of Red Cloud exit on Interstate 10 just north of the MWD Powerline Road; 775 meters (2,543 feet) west and 800 meters (2,625 feet) south of the NE corner of section 26, T. 5 S., R. 13 E., San Bernardino Base and Meridian; 33 degrees, 42 minutes and 27.1 seconds north latitude, and 115 degrees, 35 minutes and 48.8 seconds west longitude; USGS Hayfield Spring 7.5 minute topographic quadrangle; UTM 11S 0615872e 3755531n (DTM: NAD83).

RANGE IN CHARACTERISTICS:

Soil moisture control section: usually dry throughout, rarely moist in
some parts during winter, summer and early fall. The soils have a
typic-aridic soil moisture regime.

Soil temperature: 25 to 28 degrees C (77 to 82 F).

Surface rock fragments: 40 to 90 percent; with 40 to 70 percent gravel, 0
to 20 percent cobbles, 0 to 15 percent stones and 0 to 2 percent
boulders.

Control section

COMPETING SERIES: These are the Bristolake (CA) and Sheephole (CA) series. Both soils have a mean annual soil temperature of 22 to 25 degrees C, and are moist for 10 to 20 days cumulative between July and September following summer convection storms. In addition, Bristolake soils are at least moderately alkaline in the surface horizon and have an electrical conductivity (EC) of 4 to 16 dS/m and an SAR of 5 to 12 throughout most of the particle-size control section. Sheephole soils are formed in eolian material overlying alluvium with less than 15 percent rock fragments in the upper part of the particle size control section.

GEOGRAPHIC SETTING: Goldrose soils are on alluvial fans. Slopes range from 4 to 8 percent. These soils formed in alluvium from granitoid and/or gneissic rocks. Elevations range from 300 to 835 meters (984 to 2,740 feet). The climate is arid, with hot, dry summers and warm, dry winters. The mean annual precipitation is 50 to 100 millimeters (2 to 4 inches) and the mean annual air temperature is 23 to 26 degrees C (73 to 79 degrees F). The frost-free season is 360 to 365 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Carsitas and Chemwash soils. Carsitas and Chemwash soils are on fan aprons. Carsitas soils have less than 35 percent gravel in the particle-size control section. Chemwash soils have sandy-skeletal particle-size control sections dominated by fine gravel.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained; very low runoff; high saturated hydraulic conductivity.

USE AND VEGETATION: Goldrose soils are used for recreation and wildlife habitat. The present vegetation is mainly creosote bush, palo verde and ironwood.

DISTRIBUTION AND EXTENT: Colorado Desert of southeastern California. MLRA 31. These soils are of small extent.
