The Flora of Mount Rainier -- a Photographic Journey, by Susan McDougall
Cascade Mountain-ash - Sorbus scopulina var. cascadensis
Less common than the other mountain-ash species, Sitka Mountain-ash, this one can be found growing in thickets and at the edges of woods above 5500 feet, most easily seen at Sunrise, where it was photographed July 25, 2014.
