CLIMINE SERIES

The Climine series consists of very deep, well drained soils that formed in colluvium derived from mixed rocks with additions of loess high in volcanic ash. Climine soils are on mountain side slopes. Slopes are 15 to 75 percent. The mean annual precipitation is about 300 mm and the mean annual temperature is about 6 degrees C.

COMPETING SERIES: These are the Baldridge, Beehunt, Burgi, Chambeam, Fredonyer, Ginser, Glean, Lambring, Lonecabin, Pinochle, Rondowa, Shorthike, Sinker, Webfoot, Westbutte and Willynat series.

Baldridge, Burgi and Chambeam soils are dry for less than 80 consecutive days following the summer solstice. Beehunt soils have more than 65 percent rock fragments in the particle-size control section. Sinker and Westbutte soils have a lithic contact at a depth of 50 to 100. Chambeam soils have rock fragments that are dominantly channers or flagstones. Ginser and Pinochle soils have bedrock within 100 cm. Glean, Lonecabin, Shorthike, Webfoot and Willynat soils have less 18 percent clay in the particle-size control section. Lambring and Rondowa soils have a particle-size control section with more than 25 percent sand coarser than very fine sand.

GEOGRAPHIC SETTING: Climine soils are on mountain side slopes, normally on north aspects. These soils formed in colluvium from mixed rocks with additions of loess high in volcanic ash. Slopes are 15 to 75 percent. Elevations are 1,770 to 2,290 meters. The climate is cool, semiarid with cold, moist winters and warm, dry summers. The mean annual precipitation is 300 to 400 mm, mean annual temperature is 4 to 7 degrees C, 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 SATURATED HYDRAULIC CONDUCTIVITY: Well drained; rapid runoff; moderately high saturated hydraulic conductivity.

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.
