We here at SMFDR were dumbfounded by the following sights. Our hands were still trembling when we uploaded pictures for you to see — they are easily the eeriest (but also the most exciting) places in the world.

The combination of excitement and danger in these photos arouses some contradictory feelings — you are afraid to look, yet you can’t take your eyes off them. The way nature can make humans seem like they’re nothing at all makes you think of your own insignificance in the face of time.
