Parent material of basalt and andesite are most common. Snowfall accumulations average 1.2-1.5 m (4-5 feet) annually. Pseudotsuga menziesii and Abies concolor dominate the overstory while Abies amabilis and Abies concolor dominate the understory. A shrub layer, averaging 40%, is characterized by Mahonia nervosa (= var. nervosa) and Vaccinium membranaceum.
