The gathering storm~SkyWatch Friday ~082611

Thunderheads gathered up on the rim once again on our last afternoon there.  We were out by Black Canyon Lake and we could hear the thunder of the approaching storm.  The booms became closer and closer until the storm was upon us.  Skywatch Friday for August 26, 2011.
