I don't like this name so expect it to change if I can come up with something else.  The creek is unnamed and it drops off Big Devil Mountain, which already has a waterfall named after it.  Anyway, this waterfall occurs on a stream that is most likely seasonal.  The main drop appears to be around 100' in height and there are several more smaller tiers above it.  This really isn't anything to get excited about, but if you're driving up to Thornton Lakes Trailhead and look across the valley, you will see this waterfall.  It's probably possible to get to the base by either boating across the river and then bushwhacking or bushwhacking from off of Newhalem Creek Road.  If the base were reachable, this would be a very nice waterfall during the peak of snowmelt.  As is, it's mostly an afterthought.
