Rock fragments: 35 to 60 percent, mainly pebbles.

Consistence: Soft or slightly hard, dry; in some pedons subhorizons below 40 inches are hard when dry.
Silica Cementation: 1 to 15 percent durinodes or continuous brittle matrix with masses and lenses. Volume of silica cementation, pendents, or durinodes increases to over 15 percent below depths of 40 inches in most pedons.
COMPETING SERIES: These are the Baldridge(OR), Burgi(UT), Chambeam(OR), Fredonyer(CA), Ginser(OR), Glean(CA), Lambring(OR), Rondowa(T OR), Sinker(OR), St. Anthony(ID), Webfoot(OR) and Westbutte(OR) series. All these soils lack subhorizons with durinodes in a friable matrix or silica coats and pendents on rock fragments. In addition, Fredonyer, Sinker and Westbutte soils have a lithic contact at a depth of 20 to 40 inches. Baldridge, Burgi and Chambeam soils are also dry for less than 80 consecutive days following the summer solstice. Burgi soils also have more than 25 percent sand coarser than very fine sand and Chambeam soils also have rock fragments that are dominantly channers or flagstones. Ginser soils have a paralithic contact at a depth of 20 to 40 inches. Glean soils have a control section with 8 to 18 percent clay and more than 25 percent sand coarser than very fine sand. Lambring and Rondowa soils have a particle-size control section with more than 25 percent sand coarser than very fine sand. St. Anthony soils are moderately deep to a coarse sand and gravel lithologic discontinuity. Webfoot soils average 5 to 15 percent clay in the particle size control section and have a saturated layer above 40 inches for 90 or more consecutive days.
GEOGRAPHIC SETTING: Climine soils are on mountain side slopes, normally on north aspects. These soils formed in colluvium from mixed rock sources with additions of loess high in volcanic ash. Slopes are 15 to 75 percent. Elevations are 5,800 to 7,500 feet. The climate is cool, semiarid with cold, moist winters and warm, dry summers. The mean annual precipitation is 12 to 16 inches; mean annual temperature is 40 to 45 degrees F., and the frost-free season is 60 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gowjai and Wiskan series. Gowjai soils have argillic horizons. Wiskan soils are moderately deep and have argillic horizons.
DRAINAGE AND PERMEABILITY: Well drained; rapid runoff; moderate permeability.
USE AND VEGETATION: Rangeland and wildlife habitat. The present vegetation is mainly threetip sagebrush, Cusick bluegrass, basin wildrye and arrowleaf balsamroot.
DISTRIBUTION AND EXTENT: Northern Nevada. These soils are not extensive. MLRA 24.
MLRA OFFICE RESPONSIBLE: Reno, Nevada
SERIES ESTABLISHED: Humboldt County, Nevada, East Part, 1993.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - The zone from the soil surface to 25 inches. (A and AB horizon)
Particle-size control section - The zone from 10 to 40 inches (A2, A3, AB, and part of the 2Bq1 horizons).
The superactive cation exchange activity class was added in 03/2003 to the taxonomic classification by the National Soil Survey Center on request of the Reno MLRA office, without review of the soil series property data. The remainder of this document has not been updated.
