LYKORLY SERIES
The Lykorly series consists of very deep, well drained soils on fan remnants and stream terraces. These soils formed in mixed alluvium derived dominantly from sedimentary rocks. Slope is 1 to 6 percent. The mean annual precipitation is about 16 inches (406 mm) and the mean annual air temperature is about 53 degrees F (12 degrees C).

GEOGRAPHIC SETTING: Lykorly soils are on fan remnants and stream terraces at elevations of 4990 to 6500 feet (1,521 to 1,981 meters). These soils formed in alluvium derived dominantly from sedimentary rocks. Slopes range from 1 to 6 percent. The mean annual air temperature is 48 to 54 degrees F (9 to 12 degrees C). Annual precipitation is 13 to 18 inches (330 to 457 mm), and the frost-free period is 130 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Wodomont,
Disterheff,
Natank and
Yumtheska soils. Wodomont and Yumtheska soils are shallow to bedrock. Natank soils are moderately deep to bedrock. Disterheff soils have fine textured argillic horizons.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately slow or slow permeability.
USE AND VEGETATION: These soils are used for livestock grazing, wildlife habitat, and fuelwood production. The present vegetation is bottlebrush squirreltail, Wyoming big sagebrush, blue grama, muttongrass, pinyon pine and Utah juniper.
DISTRIBUTION AND EXTENT: Northern Arizona. This series is moderately extensive. MLRA is 35 and 39.
