...Put this one in the optical illusion category as well.  The shot was taken straight down.  Kurt's foot is NOT resting by a puddle.  It is hanging over Whitney face... And that puddle is really Iceberg Lake located 2,000 ft. below. 

The real reason for the picture was to capture a small bird (type unknown... hey we're just a bunch of guys, not ornithologists) that kept landing on Kurt's shoulder.  Missed it, but the scene was worth preserving anyway.
