Book Description

Excerpt from Lodgepole Pine in the Blue Mountains of Northeastern Oregon Geologically, the Blue Mountains consist of numerous layers of basalt, which weathers to heavy silts and silty clays. While these soils are often quite fertile chemically, high clay contents tend to create physical conditions unfavorable for tree growth. The soils dry early in the growing season on ridgetops and basalt rims, where erosion has left only a thin (2 to 8 inches) soil mantle.
