TYPE LOCATION: Lincoln County, Nevada; approximately 500 feet east of the southwest corner of sec. 4, T.4N., R.69E.
RANGE IN CHARACTERISTICS: The solum is 28 to 40 inches thick. The mollic epipedon is 26 to 40 inches thick. The mean annual soil temperature is 43 to 47F., and the mean summer soil temperature is 59 to 64F. These soils are usually dry during the summer and fall months. The A and B horizons have hue of 10YR or 7.5YR, value of 4 or 5 dry and 2 or 3 moist, and chroma of 2 or 3. The upper 20 inches of the argillic horizon has an average clay content of 25 to 35 percent, and 20 to 35 percent coarse fragments by volume. The argillic horizon is 20 to 28 inches thick. The solum is neutral (pH 6.6 to 7.3). The Al horizon has weak or moderate, medium or fine, granular or subangular blocky structure, or is massive. It is primarily gravelly fine sandy loam, but is gravelly loam or gravelly sandy loam in some pedons. Stones on the surface include classes 1 and 2 stoniness. The B2t horizon is primarily gravelly clay loam, but ranges to gravelly sandy clay loam, or gravelly heavy loam. It has weak to strong, medium or coarse subangular blocky structure, depending upon the gravel content. The C horizon has value of 6 or 7 dry and 4 or 5 moist, and chroma of 2 or 3. It has slight to violent effervescence and has few to many, fine to coarse lime filaments or coatings on pebbles. This horizon is mildly to moderately alkaline (pH 7.8 to 8.4) .
COMPETING SERIES: These are the Clegg and Gross series. Clegg soils have less than 20 percent coarse fragments in the B2t horizons. Gross soils have bedrock at depths of 20 to 40 inches.
GEOGRAPHIC SETTING: Lize soils are on moderately steep and steep terrace side slopeg at elevations of 6,300 to 7,200 feet. Slopes are 15 to 50 percent. The soils formed in gravelly loamy alluvium primarily from rhyodacitic ignimbrites. The climate ig cool, continental. The mean annual temperature is about 40 to 45F., mean summer temperature is 60 to 62F., and the average frost-free season is about 100 days. The mean annual precipitation is 12 to 14 incheg, with most of it coming as snow.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bagket, Decathon, Uomegtake, Satt, and Tica soils. Basket soils have more than 35 percent coarse fragmentg in the 10- to 40-inch section. Decathon soils have ochric epipedons and indurated duripans. Uomestake soils have clayey-skeletal argillic horizons and weakly cemented Csica horizons. Satt soils have cryic temperature regime and indurated duripans. Tica soils have fine textured argillic horizons and lithic contacts at depths less than 20 inches.
DRAINAGE AND PERMIABILITY: Well-drained; medium or rapid runoff; moderately slow permeability.
USE AND VEGETATION: Used for livestock grazing and wildlife habitat. The principal plants are pinyon and juniper trees and big sagebrush, but also include bitterbrush, bluegrasses, needlegrass, and some black sagebrush.
DISTRIBUTION AND EXTENT: East-central Nevada. Lize soils are inextensive (about 6,000 acres).
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California
SERIES ESTABLISHED: Lincoln County (Meadow Valley Area), Nevada, 1971.
REMARKS: Lize soils were formerly classified as Chestnut soils.
