Particle-size control section - Clay content: 18 to 30 percent.
Rock fragments: 35 to 60 percent, mainly pebbles.
A horizon - Value: 4 or 5 dry, 2 or 3 moist.
Chroma: 2 or 3.
Bt horizon - Value: 4 or 5 dry, 3 or 4 moist.

Clay content: 22 to 35 percent.
Rock fragments: 35 to 60 percent, mainly pebbles.

COMPETING SERIES: These are the Bushpark, Copenhaver, Donkehill, Hogmalat, Maygal, Mosroc, Nielson, Nieman, Notstew and Thiefridge series.
Bushpark soils have a udic soil moisture regime. Copenhaver, Donkehill, Neiman and Nielsen soils have a mean annual soil temperature less than 6 degrees C. Hogmalat soils are strongly to medium acid throughout. Maygal and Thiefridge soils have bedrock at 36 to 50 cm. Mosroc soils formed in weathered material derived dominantly from granite and the mollic epipedon includes the entire argillic horizon. Notstew soils have more than 35 percent clay in the argillic horizon.
GEOGRAPHIC SETTING: Layview soils are on convex mountain crests, summits, shoulders and side slopes. These soils formed in residuum and colluvium from rhyolite, andesite, chert and tuffaceous rocks. Slopes are 4 to 75 percent. Elevations are 2,134 to 3,048 meters. The climate is cool, semi-arid with a mean annual precipitation ranging from 300 to 400 mm; mean annual temperature is 5 to 6 degrees C.,and the frost-free season is 50 to 80 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Hapgood, Packer, and Mosquet series. Hapgood and Packer are deep soils, Mosquet is clayey-skeletal and ruptic.
DRAINAGE AND PERMEABILITY: Well drained; runoff is medium or very rapid; moderately slow permeabiltiy; moderately high saturated hydraulic conductivity.
USE AND VEGETATION: Rangeland and wildlife habitat. The present vegetation is Thurber needlegrass, Sandberg bluegrass, Idaho fescue, and low sagebrush.
DISTRIBUTION AND EXTENT: Central Nevada. Layview soils are of small extent. MLRA 27, 28B, 24.
MLRA OFFICE RESPONSIBLE: Reno, Nevada
SERIES ESTABLISHED: Lander County, Nevada, South Part, 1985.
