Interesting "medium-sized" hydrothermal explosion today at Yellowstone. It is being played down a bit. . . but the explosion damaged one of the boardwalks and it's railings, and very nearly damaged a bunch of tourists. . . I'll bet this is a day they won't soon forget.

I am hearing that this type of explosion is not especially unusual at Yellowstone. . . but it looks pretty spectacular to me.
Luckily, the explosion appeared to occur a ways off from one of the boardwalks, instead of right under it. . . or the story might have had a bit of a different ending. . .
