Name of Waterfall

Cooper Falls


Between Cooper Lake and the Cle Elum River, the Cooper River courses down an impressive canyon, teeming with small waterfalls and cascades. However, before it gets to all that, it drops over this 40 foot fanning-cascade. Accounts from Kayakers who frequent the river below the falls say its 50 feet tall, but it looks to be a bit less than that to me. The perspective achieved from the base of the falls really doesn't show how long the falls are either. From head on, the falls appear to be a relatively straight forward fan-shaped waterfall, but if one were to ford the river (don't do it unless the river is low), the falls would reveal themselves to be a long, sloping cascade, with the majority of the water falling off to the side of the falls, rather than straight ahead. This phenomenon becomes much more obvious when the river is running low late in the year.
