The more than 4 million milestone visitors to Yellowstone National Park this past season included me. What an amazing place!  This is West Thumb Geyser Basin, located on Yellowstone Lake, the largest lake over 8,000 feet elevation in North America. Numerous steamy hot springs in varying colors, rimmed with delicate crystals, make the walk other-worldly.
