March 2009, Yosemite National Park, California
This view from within Yosemite's infamous Wawona Tunnel made me feel as though I was being transported through some sort of gigantic time machine. The view upon exiting the tunnel into Yosemite Valley will make you think as though you have arrived on a completely different planet. It is indescribable.
Built in 1933, the tunnel is about 3/4 of a mile long. The trick in pulling off this shot is not to get run over in the process. I'm happy to report that I succeeded.
