As the light increased, I discovered around me an ocean of mist, which by chance reached up exactly to the base of the tower, and shut out every vestige of the earth, while I was left floating on this fragment of the wreck of a world, on my carved plank, in cloudland...
All around beneath me was spread for a hundred miles on every side, as far as the eye could reach, an undulating country of clouds, answering in the varied swell of its surface to the terrestrial world it veiled. It was such a country as we might see in dreams, with all the delights of paradise.
- Henry David Thoreau, A Week on the Concord and Merrimack Rivers
