In Americas first national park, Chuck Larsen of Pacific Palisades snapped this surreal scene at Biscuit Geyser. It was October of last year, and Yellowstone was starting to cool down and shut down, but its hot spots were still percolating. I was standing on a boardwalk and caught the picture of the three, he said. Its a tribute to the mighty geysers of Yellowstone but also to the time-honored tradition of taking the family to see this wonder of the West. Larsen and a friend have been photo-touring national parks for several years. He used a Canon Rebel XTi.
