Berthahill soil series
Typical profile of a Berthahill soil. The volcanic ash mantle extends from the surface of the mineral soil material to a depth of about 50 to 60 centimeters. (Soil Survey of Clearwater Area, Idaho; by Glenn Hoffman, Natural Resources Conservation Service)
The Berthahill series consists of very deep, well drained soils formed in material weathered from quartzite with a thick mantle of volcanic ash. These soils are on mountain slopes, summits, and ridges. Permeability is moderate. Slopes range from 15 to 75 percent. The mean annual precipitation is about 47 inches and the average annual air temperature is about 40 degrees F.
TAXONOMIC CLASS: Medial over loamy-skeletal, amorphic over isotic Typic Haplocryands
Average annual soil temperature - 38 to 41 degrees F. Cryic temperature regime.
Soil moisture control section - usually moist year round and not dry for 30 consecutive days from June to October. Udic moisture regime.
Thickness of volcanic ash mantle - 14 to 19 inches
Volcanic glass content in the 0.02 to 2.0 mm fraction - 15 to 50 percent
Acid-oxlate extractable A1+1/2 Fe - 1.5 to 3.6 percent
Phosphorous retention - 55 to 90 percent
15-bar water retention - 12.0 to 18.0 percent on air-dried samples
USE AND VEGETATION: These soils are used for timber production, recreation, and wildlife habitat. Potential natural vegetation is subalpine fir, Engelmann spruce, Douglas fir, lodgepole pine, and grand fir with an understory of queencup beadlily, mountain arnica, prince's pine, wild ginger, common pink wintergreen, coolwort foamflower, western goldenthread, rattlesnake plantain, common beargrass, rustyleaf menziesia, myrtle pachystima, and blue huckleberry.
DISTRIBUTION AND EXTENT: North Central Idaho. These soils are not extensive.
