5. Painted Dunes
Another curious place for you to visit and see in the United States is called Lassen National Park. What you see may be easily compared to the views usually seen in the pictures taken on Mars or some other planet. The park attracts people since there are the legendary Painted Dunes. These Californian pumice fields are full of different colors and hues. The effect is the result of oxidation of the ash that has a volcanic origin.
