American Northwest Trip, 2017: Upper Geyser Basin in Yellowstone

These photos are from my hike of the Upper Geyser Basin in Yellowstone National Park, a geyser-rich geothermal area that includes the Old Faithful, Beehive, and Castle geysers, along with more than four-hundred others. As I may have mentioned in previous posts, walking among all of these cones, boiling springs, bursting geysers, and steam plumes really drives home the reality that you are standing on top of a super volcano. I didn’t have time to explore the entire basin, but I saw a good portion of it. Toward the end of my hike I caught the eruption of the Lion Geyser from a distance, documented in a couple of the photos.
