| Note: | I went to check it out while hiking to Black Sand Basin. While I was next to it, I felt the ground shake like an explosion went off under my feet. Then, it aggressively started to boil. It was super weird. I've never felt something like that in all the time I've spent in the park, so I figured it was noteworthy. |
