Fountain Paint Pot
This is a bison calf on the walkway at Fountain Paint Pot. I did not zoom in; (s)he really was that close to us. Before you write a comment chastising us for putting Liam (and the bison) in danger, let me say that we had absolutely no choice. The bison were surrounding us, and they kept getting closer. There was nowhere to go. (That didn't stop a woman who saw this happen from giving us a good talking-to. I guess she thought we should've used our jet packs to blast up and away.)
This is Old Faithful right at the end of an eruption:
I couldn't help taking this video of the Firehole River. The scenery and the sounds were too beautiful.
