From the U.S. Department of the Interior:

This picture from Great Sand Dunes National Park and Preserve in #Colorado has everything! Fall colors, massive sand dunes and snow capped mountains showcase this marvel of the West. Visiting here is an experience unlike anywhere else. Did you know you can sled down the dunes? Photo by National Park Service. — at Great Sand Dunes National Park and Preserve.
