TYPE LOCATION: Eureka County, Nevada; approximately 32 miles northwest of Eureka; about l,200 feet north and 800 feet west of
the southeast corner of section 32., T., 23 N., R. 50 E.

summer and early fall.
Soil temperature - 43 to 47 degrees F.
Average summer soil temperature - 52 to 56 degrees F.
Control section - Texture: Extremely gravelly loam or extremely gravelly sandy loam.
Clay content: l2 to 25 percent.
Rock fragments: 60 to 80 percent, mostly pebbles, when averaged. Carbonates: 60 to 80 percent calcium carbonate equivalent.
Mollic epipedon - l0 to l4 inches.
Depth to bedrock - 20 to 40 inches.
A horizon - Value: 4 or 5 dry.
Chroma: 2 or 3.
Bw horizon - Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 3 or 4.

COMPETING SERIES: These are the
Dekoom, Lavon,
Redmanson, and
Urtah series. Dekoom soils are very deep and have 40 to 60
percent calcium carbonate equivalent. Lavon soils have visible secondary carbonates. Redmanson soils lack bedrock within 40
inches. Urtah soils are dry more than 60 consecutive days in the summer and have mean summer temperatures of 56 to 59 degrees F.
GEOGRAPHIC SETTING: Hatur soils are on mountain side slopes.
These soils formed in residuum and colluvium from limestone
or dolostone. Slopes are l5 to 50 percent. Elevations are
7,500 to 9,500 feet. The climate is cool, continental, with
cold, wet winters and cool, dry summers. The mean annual precipitation is 16 to 26 inches, that comes mostly as snow; mean annual temperature is 40 to 43 degrees F., and the frost-free
season is about 60 days.
GEOGRAPHICALLY ASSOCIATED SOILS: This is
Haunchee soils.
Haunchee soils have bedrock within 20 inches.
DRAINAGE AND PERMEABILITY: Well drained; medium or rapid
runoff; moderate permeability.
USE AND VEGETATION: Rangeland and wildlife habitat. The
present vegetation is mountain big sagebrush, Idaho fescue
and curlleaf mountainmahogany.
DISTRIBUTION AND EXTENT: North-central Nevada. These soils
MLRA OFFICE RESPONSIBLE: Reno, Nevada
are moderately extensive.
SERIES ESTABLISHED: Eureka County Area, Nevada, l983.
DIAGNOSTIC HORIZONS AND FEATURES RECOGNIZED IN THIS PEDON ARE:
Mollic epipedon - The zone from the soil surface to about 10
inches (the A1 and A2 horizons).
Lithic contact - The boundary at about 35 inches (the R horizon).
Particle-size control section - The zone from 10 to about 35
inches (the Bw and C horizons).
