Future Cities: Mesa Verde
Mesa Verde boggled my mind. Here was a culture from AD 700-1300, such a long time ago, that created these villages inside of cliffs. (Click to enlarge the picture to see them!) At the same time, these cities in cliffs seem to come from the future too. At some point, we might want to find every nook and cranny to put people in, and also to live together with nature's natural formations rather than overlaying our cities on top of them.
