I think so. It was taken on a trip to Colorado a couple years ago. There was some story about the sand being carried by the river, the wind blowing it back, and the cycle repeating.
The top one was taken in St. Thomas USVI; Magen's beach. The rest were taken in our back yard.
Actually the sand is wind blown and drops to the ground as the winds lift over tbe mountains in the background. The unique situation earned it National Park status.
