Description: This association occurs at an average of 1045 m (3431 feet) elevation on northerly aspects with mean slope of 29%. Parent materials are typically basalt, andesite, pumice, ash, granite, or mixed intrusives with deep surface soils. Tree canopy cover is dominated by <i>Pseudotsuga menziesii</i> (36%) and <i>Tsuga heterophylla</i> (20%).
