Tourists walk along the boardwalk at the Grand Prismatic Spring in Yellowstone National Park, Wyoming.
Easily one of the most photographed sites in Yellowstone, the Grand Prismatic Spring is a remarkable display of color seen from both up close and above. Finding a unique angle can be pretty tricky. Even from this out-of-the-way location there were dozens of other photographers coming in and out. Regardless, it remains an incredible site to see if nothing else than for its enormous size.
