Colosseum of Nature

-
What is this inexplicable object that cannot be a mountain but has the height of a mountain, that cannot be a wall but has the shape of a wall? It's a mountain and a wall at the same time; it's the most mysterious edifice of the most mysterious of architects; it's nature's Colosseum.

Victor Hugo
