There's not a whole lot of water coming off of Bridalveil Fall, is there?  It's hard to believe this is a photo taken in May.  Bridalveil usually runs year round.  I wonder if it will dry up this year.  It's hard to imagine it won't considering how low it looks already.  Maybe the source is an underground spring?  Dunno.  Most creeks and rivers in Yosemite come from snow melt.  I imagine Bridalveil Creek is the same.  Guess I'll have to google it.
