Rock solid. Between a rock and a hard place. Hard as a rock. So many of expressions and clichés are built upon the durability of rocks.

And yet, wandering through the maze that makes up the Lower Antelope Canyon in Page, Arizona, one can only be struck by how malleable rock truly is.

It was water that carved out the canyon. And with every summer rainstorm, it is water that continues to shape and reshape the place.

The result is visually stunning, of course — sunlight giving life to a wavy, rippling red-rock landscape reaching dozens of metres deep.
