KLECKNER SERIES

The Kleckner series consists of very deep, well drained soils that formed in alluvium derived from mixed rocks or in colluvium derived from tuff or rhyolite. Kleckner soils are on fan remnants and hills. Slopes are 2 to 50 percent. The mean annual precipitation is about 280 mm and the mean annual temperature is about 6 degrees C.

TYPE LOCATION: Elko County, Nevada; about 14 miles southeast of Wildhorse Reservoir; about 660 feet west of the northeast corner of section 15, T. 42 N., R. 57 E.; USGS Mount Ichabod 7.5 minute topographic quadrangle; latitude 41 degrees 32 minutes 23 seconds N and longitude 115 degrees 31 minutes 16 seconds W; WGS84 Decimal Degrees 41.5397222 latitude, -115.5211111 longitude.

Durinodes: 20 to 40 percent weakly cemented durinodes in the Bq1 horizon.
Consistence: hard or very hard and firm with a brittle manner of failure in the Bq2 horizon.
Reaction: Neutral through moderately alkaline.
Other features: Some pedons have secondary carbonates in the Bq2 horizon; some pedons lack durinodes or a brittle matrix but have silica coats or pendants on rock fragments.

COMPETING SERIES: These are the Bagard, Blitzen, Fera, Gosumi, Quarz, Slaven, and Snellby series.

Bagard soils are dominated by cobbles and stones and do not have durinodes or a firm, brittle matrix between depths of 100 and 150 cm. Blitzen soils are moderately deep to paralithic contacts. Fera and Gosumi soils are deep to lithic contacts. Quarz, Slaven, and Snellby soils are moderately deep to lithic contacts.

GEOGRAPHIC SETTING: Kleckner soils are on fan remnants and hills. These soils formed in alluvium derived from mixed rocks or in colluvium derived from tuff or rhyolite. Slopes are 2 to 50 percent. Elevations range from 1,555 to 2,380 meters. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 250 to 300 mm, mean annual temperature is 5 to 7 degrees C., and the frost-free period is 70 to 100 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Quarz soil and the Akler, Bilbo, Cotant, Donna, and Stampede soils. Akler and Cotant soils are shallow to paralithic contacts. Bilbo soils have ochric epipedons and do not have Bq horizons. Donna and Stampede soils are moderately deep to indurated duripans.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; very high surface runoff; moderately low saturated hydraulic conductivity.

USE AND VEGETATION: Kleckner soils are used for rangeland and wildlife habitat. The vegetation is mainly basin big sagebrush, Wyoming big sagebrush, bluebunch wheatgrass, and basin wildrye.

DISTRIBUTION AND EXTENT: Northeastern Nevada. These soils are moderately extensive. MLRA 25.
