LOCATION KINGSBEACH CA NVEstablished Series
The Kingsbeach series consists of very deep, moderately well drained soils that formed in alluvium and/or colluvium derived from andesite over lacustrine deposits. The Kingsbeach soils are on alluvial fan. Slopes range from 2 to 15 percent. The mean annual precipitation is about 635 millimeters and the mean annual air temperature is about 6 degrees C.

COMPETING SERIES: These are the Deerhill soils. Deerhill soils have greater than 60 percent parafragments in the lower part and is on hillslopes and mountainsides.
GEOGRAPHIC SETTING: The Kingsbeach soils are on alluvial fans. Slopes range from 2 to 15 percent. These soils formed in alluvium and colluvium derived from andesite over lacustrine deposits. Elevation is 1894 to 2046 meters. The climate is subhumid with warm dry summers and cold wet winters. The mean annual precipitation is 580 to 840 millimeters and the mean annual air temperature is 5 to 8 degrees C. The frost free season is 30 to 80 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Jorge and Tahoma soils. The Jorge soils are loamy-skeletal and are on hillsides and mountain slopes and the Tahoma soils are on mountain slopes and underlain by residuum derived from andesitic lahar.
DRAINAGE AND PERMEABILITY: Moderately well drained, very slow permeability, medium runoff. These soils are not flooded or ponded
