2 Half Dome Waterfalls(?)

I never saw this Half Dome view before: 2 Waterfalls coming off Half Dome. Viewed from Illilouette Ridge 6/22/2011. Note [10/2/12]: Looking at this again, a year later, I am thinking that the top 'fall' is really a skinny snow field. Magnification seems to bear this out. The bottom fall is legitimate, though, even under magnification.
