COMPETING SERIES: These are the Bluegulch(T ID), Cewat(NV), Darkcanyon(OR), Felcher(OR), Finley(WA), Graveya(T ID), Kiona(WA), Mackey(ID), Minat(NV), Nibbs(ID), Veet(NV), Veta(NV) and Wifton(T NV) soils. Bluegulch soils have cambic horizons with 18 to 26 percent clay and Bk horizons with extremely gravelly loam or sandy loam. Cewat soils are less than 40 inches deep to bedrock and have more than 15 percent clay in the control section. Darkcanyon and Mackey soils are 20 to 40 inches deep to bedrock. Felcher soils have bedrock at 20 to 40 inches and contain 20 to 35 percent clay. Finley soils have lime-silica pendants on rock fragments in the cambic horizon and are 20 to 40 inches deep to sandy 2C horizons. Graveya soils contain 24 to 30 percent clay in the Bw horizon. Kiona, Minat and Veet soils are less than 30 inches deep to lime. In addition, the Kiona soils also have mainly cobbles in the control section; Minat soils have 15 to 27 percent clay in the particle- size control section; and Veet soils have a sola 10 to 20 inches thick. Nibbs soils are 10 to 15 inches deep to carbonates and are underlain by stratified sand and gravel. Veta soils have combined thickness of A and Bw horizons of 12 to 20 inches. Wifton soils are very deep and lack Bkqm horizons.
GEOGRAPHIC SETTING: Panlee soils are on hill and mountain side slopes. These soils formed in residuum and colluvium weathered from mixed rock sources with a small component of loess and volcanic ash. Slopes are 8 to 50 percent. Elevations are 4,300 to 6,500 feet. The climate is cool, semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 8 to 10 inches; mean annual temperature is 45 to 50 degrees F., and the frost-free season is 90 to 120 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gowjai, Old Camp and Atlow soils. Gowjai soils have a mollic epipedon and a frigid temperature regime. Old Camp and Atlow soils are shallow over bedrock.
DRAINAGE AND PERMEABILITY: Well drained; medium or rapid runoff; moderate permeability.
USE AND VEGETATION; Rangeland and wildlife habitat. The present vegetation is mainly Wyoming big sagebrush and basin big sagebrush, Sandberg bluegrass, bottlebrush squirreltail and needleandthread.
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:
Ochric epipedon - The zone from the soil surface to 10 inches (A1 and A2 horizons).
Cambic horizon - The zone from 10 to 29 inches (Bw horizon).
Xerollic intergrades - Meets soil moisture regime and organic carbon requirement for "Xerollic".
Particle-size control section - The zone from 10 to 40 inches (Bw, Bq and part of the Bqk 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.
