🇺🇸"Wave", Arizona, USA.
Approximately 180 to 190 million years ago, one of the greatest geological sites on our planet began to form in the USA. In the Coyote Buttes ravine on the border of Utah and Arizona, at an altitude of 1,592 meters above sea level, an “Arizona Wave" formed, which eventually became one of the most popular destinations among hiking enthusiasts. This unique mountain measuring 19 m wide and 36 m long has an incredible undulating appearance and a massive sandy structure . In a sense, this is a snapshot of how natural forces affect the environment.
