Doubtful Creek is a fairly large creek that drains Doubftul Lake on the eastern side of Cascade Pass.  Almost immediately upon exiting the lake, the creek drops over this tall, multi-tiered, complex waterfall.  The bottom of the falls can be glimpsed through the trees as the trail begins to drop down towards the creek crossing at Doubtful Creek Falls.  There is a trail that drops down to the lake from the Sahale Arm Trail, so it should be possible (although I have no idea how difficult) to follow the creek down to the top of the falls and perhaps climb down from there.  From the trail, the waterfall isn't horribly exciting because the views are fairly distant but from up close this would be a great waterfall.
