In this quiet moment I watch a camel handler appear from the dunes to the east, make their way unhurriedly past me, and finally disappear among the dunes to my west. This scene could be from a month or a year ago. It could be one hundred years old, even one thousand.

But the form of these dunes is not the same as the dunes of a thousand years ago. These are not the dunes of one hundred years ago, or even a year. This landscape is ever changing, always reshaping itself.
