- Grand Prismatic Spring, Yellowstone National Park
Most people see this famous hot spring (one of the world's largest) only from ground level. However, a short but steep hike up a neighboring hill gives you a panoramic view. I like the range of colors (from the foreground, the spring itself, and the forested background), and the way in which the pedestrian boardwalk at the bottom-right leads your eye towards the spring. https://en.wikipedia.org/wiki/Grand_Prismatic_Spring (May 23, 2013.

A popular subject of photographers; this is probably the world's most photographed barn. (May 27, 2013. Nikon D5000, HDR-processing from a 3-shot bracketed exposure @ f/16, 34mm, ISO 200.) - Tap!
As in three of the previous four years' 'favorites' albums, there's a Brazilian Jiu-Jitsu photo in this year's album. This photo - from the 2013 World Championships - shows Woolf Barnato (Ralph Gracie Jiu-Jitsu, San Francisco) submitting an opponent (with a choke), en route to winning the purple belt light-feather division.
