The Crestal Alpine-Subalpine Zone ecoregion includes the highest parts of the rugged Canadian Rockies. Maximum elevations are sufficiently high to trap Pacific moisture and exceed 10,400 feet. Ecoregion 41b is characterized and differentiated from lower areas by its heavy precipitation, active glaciers, thick winter snow pack, very short growing season, numerous tarns, and mixed high elevation climax vegetation. It is similar to the High Northern Rockies (15h), the High Idaho Batholith (16h), and the Alpine Zone (17h) that occur in different level III ecoregions. A variety of rock underlies the ecoregion, and colluvium, talus, and rock outcrops are common. Ecoregion 41b extends into Canada.
