Interesting "slab" waterfall on Copper Creek along the trail to the Green Giant Buttress. The waterfall is an important landmark when approaching the buttress. Climb up along the right side of the falls, and look for a narrow, somewhat overgrown rock chute leading up from the trail - this is the route to the base of the buttress. You can continue up the faint dirt trail, but it will only take you up into the brush and slide alder where it eventually disappears. We discovered that the hard way.
