This is not the grand canyon.

It is also not a hole in the ground. The features in the middle of the photograph are mountains, not canyons. Seems appropriate that the landscape should deceive us (or me at least). This is, after all. the land of the Hopi people who managed to deceive Mr Sapir & Mr Whorf into dreaming up the Sapir-Whorf hypothesis, predicated on the idea that the Hopi have no concept of time. Actually they have a quite elaborate concept of time. Perhaps Whorf suffered from too much peyote.

Possibly Whorf-like, I wander off into the philosophy of holes. Philosophically speaking it is odd that we refer to holes as things, when they are really the absence of something. The photograph appeals to me. I look at it and see a canyon, a hole, the absence of something. Then I look again and it has turned into a  mountain.
