Sitting in the Grand Prismatic steam, Yellowstone
This is one of my favorite photos of my trip. Perhaps because it combines the beauty of a vibrant thermal pool and the simplicity of watching people enjoy it or hide from it. Anyway, I love the way some of the thermal pools reflect the bacteria colorations in the steam as it rises up. In the case of the Grand Prismatic Spring, which has very vivid blues and oranges, the steam is also colorful but not as vibrant. I love the way people interact with the pools and steam, either watching it in awe or shielding their face from the unpleasant smells.
