In the Washington Cascades (including Wenatchee Province), it is often the major tree species and is sometimes the only one present (especially on talus). Frequently the authors have traveled through forests containing little or no sub- alpine fir, only to come upon inter- vening talus or slide areas where it is abundant. This phenomenon is.
