Stone Wave (The Wave), USA
The spectacle, which consists of enormous “licked” arrays of red stone on the border between Arizona and Utah. The stone is actually a sand, which is for 190 million years becomes caked and turned into rock-like monolith. This place is not very well known among tourists, because it can get there on foot, must go more than 5 kilometers, and access is strictly regulated so as not to spread through the pebbles.
