Rock waves

Gantrisch Nature Park in Switzerland

Les Recardets, a small summit in the Gantrisch Nature Park. Gantrisch fulfills all the conditions to be part of the International Dark-Sky Park, just as the Grand Canyon National Park or the Death Valley, to cite a few.
This picture was taken before sunset, with strange and beautiful colors over these mountaines, who look like waves to me! Switzerland is a very, very wonderful country!
