SANTRICK SERIES

The Santrick series consists of moderately deep, excessively drained, rapidly permeable soils that formed in sandy eolian deposits, alluvium and residuum derived from Navajo sandstone. These soils are on dunes on structural benches with slopes of 2 to 30 percent. Average annual precipitation is 10 inches (254 mm) and mean annual air temperature is about 49 degrees F (9.4 degrees C).

TAXONOMIC CLASS: Siliceous, mesic Ustic Torripsamments

TYPICAL PEDON: Santrick loamy fine sand-rangeland. (Colors are for dry soil unless otherwise stated). Surface fragments: 10 percent rounded gravel-sized ironstone nodules

A--0 to 4 inches (0 to 10 cm); reddish yellow (7.5YR 6/6) loamy fine sand, brown (7.5YR 4/4) moist; weak fine subangular blocky structure; very friable, loose, nonsticky and nonplastic; common very fine and few fine roots; 5 percent rounded gravel-sized ironstone nodules; noneffervescent; neutral (pH 6.6); clear smooth boundary. (2 to 6 inches or 5 to 15 cm thick)

C1--4 to 12 inches (10 to 30 cm); reddish brown (5YR 5/4) loamy fine sand, reddish brown (5YR 4/4) moist; weak medium subangular blocky structure; very friable, loose, nonsticky and nonplastic; common very fine and few fine roots; 5 percent rounded gravel-sized ironstone nodules; noneffervescent; neutral (pH 6.8); clear smooth boundary. (6 to 10 inches or 15 to 25 cm thick)

C2--12 to 22 inches (30 to 56 cm); reddish yellow (5YR 6/6) loamy fine sand, light reddish brown (5YR 6/4) moist; weak medium subangular blocky structure; very friable, loose, nonsticky and nonplastic; common very fine and few fine roots; 5 percent rounded gravel-sized ironstone nodules; noneffervescent; neutral (pH 6.8); clear smooth boundary. (8 to 15 inches or 20 to 38 cm thick)

C3--22 to 28 inches (56 to 71 cm); reddish yellow (5YR 6/6) loamy fine sand, light reddish brown (5YR 6/4) moist; massive; few very fine roots; 5 percent rounded gravel-sized ironstone nodules; noneffervescent; neutral (pH 6.8); abrupt smooth boundary. (4 to 9 inches or 10 to 23 cm thick)

R--28 inches (71 cm); Navajo Formation sandstone bedrock.

TYPE LOCATION: Garfield County, Utah; Grand Staircase-Escalante National Monument; about 1000 feet south and 1400 feet east of the southwest corner of section 33, Township 35 south, Range 5 East; this pedon is an unsurveyed area of Township 36 South and Range 5 East in Big Spencer Flat along the Old Sheffield Road; Red Breaks Quadrangle; latitude 37 degrees 42 minutes 40.56 seconds North and longitude 111 degrees 21 minutes 51.89 seconds West, NAD 83.

RANGE IN CHARACTERISTICS:
Soil moisture - Usually dry, intermittently moist in some part of the soil moisture section July through October and December through March. Ustic aridic moisture regime.

Soil temperature - 47 to 56 degrees F (8.3 to 13.3 degrees C).

Depth to bedrock - 20 to 40 inches (51 to 102 cm)(lithic)

Particle-size control section:

Clay content: 1 to 10 percent

A horizon
Hue: 7.5YR, 10YR
Value: 5 to 7 dry, 4 to 6 moist
Chroma: 3 to 6, dry or moist

C horizon
Hue: 5YR, 7.5YR, 10YR
Value: 4 to 7 dry, 4 to 6 moist
Chroma: 3 to 6, dry or moist
Textures: fine sand, loamy fine sand, sand, loamy sand
Reaction: neutral to moderately alkaline
Other features: some pedons have thin Cr horizons formed in residuum from Navajo sandstone

COMPETING SERIES: These are the Bispen (UT), Mespun (UT), and Reepo series. Bispen soils are deep (40 to 60 inches) to Navajo sandstone bedrock. Mespun soils are very deep (more than 60 inches deep). Reepo soils are located in MLRA 34 and are subject to average annual freezing 195 days and viewed as geographically unique for extrapolating resource inventories and the results of research.

GEOGRAPHIC SETTING: Santrick soils are on dunes on structural benches at elevations of 5,000 to 7,000 feet (1,533 to 2,134 meters). Slopes range from 1 to 30 percent. These soils formed in sandy eolian deposits, alluvium, and residuum derived from Navajo sandstone. The mean annual precipitation is 9 to 14 inches (229 to 356 mm). The mean annual air temperature is 45 to 54 degrees F (7.2 to 12.2 degrees C). The frost-free period is 120 to 165 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Nalcase, Bispen, and Mespun soils. Nalcase soils are shallow and very shallow to Navajo sandstone. Bispen soils are deep to Navajo sandstone, and Mespun soils are very deep.

DRAINAGE AND PERMEABILITY: Excessively drained, low runoff; rapid permeability above the bedrock.

USE AND VEGETATION: These soils are used mainly for rangeland, wildlife habitat and recreation. Potential native vegetation is Wyoming big sagebrush, four-wing saltbush, Cutler mormontea, Indian ricegrass, needleandthread, and galleta. These soils have been correlated to the Semidesert Sandy Loam (Wyoming Big Sagebrush) 035XY216UT ecological site.

DISTRIBUTION AND EXTENT: South-Central Utah. The soils of this series are not extensive (less than 10,000 acres). MLRA 35.

SERIES ESTABLISHED: Grand Staircase-Escalante National Monument Soil Survey, Garfield County, Utah, 2004.

REMARKS: Diagnostic horizons and features recognized in this pedon area:

Ochric epipedon - the zone from the surface to 4 inches (A horizon)

Siliceous mineralogy - soils formed directly from Navajo sandstone contains more than 90 percent silica minerals (dominantly quartz).

Lithic contact - the boundary with hard Navajo sandstone at about 28 inches (R layer)

Classified according to Soil Taxonomy, Second Edition, 1999; Keys to Soil Taxonomy, Twelfth Edition, 2014.
