quarry at the southeastern corner of Mt. Adams........June 12, 2005.
Seen at a number of drier sites on the south and southeastern
sides of Mt. Adams, this species can develop a fairly thick trunk and attain
heights of 20' and more. I have yet to see any of this species flower
this season. The photo at right shows Scouler's willow with some fall color (Willows often are yellow in color in the fall.) near Willard Springs, Conboy Lake National Wildlife Refuge.....October 23, 2023.

What may be scouler's willow as seen at about 6800' at the head of the Lewis River and on the base of the terminal moraine of the Adams Glacier, Mt. Adams Wilderness......July 19, 2018. The ovaries appear to be hairy while the lower surface of the leaves are glaucous. This seems a bit high for this species, although black cottonwood can be found 500' higher at this location. Barclay's willow is also found here.
