COMPETING SERIES: There are currently no other series in this family.
GEOGRAPHIC SETTING: Mysol soils are on lake plains and alluvial flats. These soils formed in lacustrine deposits over alluvium derived from mixed rocks. Slopes are 0 to 2 percent. Elevations range from 5,600 to 6,200 feet. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 5 to 8 inches, the mean annual temperature is 45 to 50 degrees F., and the frost-free period is 100 to 120 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Idway, Kawich and Benin soils. Idway soils are coarse-loamy over sandy or sandy-skeletal. Kawich soils are sandy, occur on stable dunes, and do not have durinodes. Benin soils are fine-textured and do not have durinodes.
DRAINAGE AND PERMEABILITY: Well drained; very slow or ponded runoff; slow permeability.
USE AND VEGETATION: Mysol soils are used for rangeland and wildlife habitat. The present vegetation is mainly shadscale, bottlebrush squirreltail, and Indian ricegrass.
DISTRIBUTION AND EXTENT: Eastern Nevada. These soils are moderately extensive. MLRA 28B.
MLRA OFFICE RESPONSIBLE: Reno, Nevada.
SERIES ESTABLISHED: Elko County, Nevada, Southeast Part, 1994.
REMARKS: The revision of April 2001 updated the taxonomic class from Fine-loamy over sandy or sandy-skeletal, mixed, calcareous, mesic Haploduridic Torriorthents by recognizing the presence of a calcic horizon.
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - The zone from the soil surface to a depth of 5 inches (A1 and A2 horizons).
Durinodes - The zone from 17 to 54 inches (Bqk1, 2Bqk2, and 2Bqk3 horizons).
Calcic horizon - The zone from 31 to 54 inches (2Bqk2 and 2Bqk3 horizons).
Major lithologic discontinuity - The abrupt change to sandy material at 31 inches (2Bqk2 and 2Bqk3 horizons).
Particle-size control section - The zone from 10 to 40 inches (Bqk1 horizon and parts of the ABk and 2Bqk2 horizons).
