Photo taken at: Great Sand Dunes National Park and Preserve
Click on the image for the video clip of the sand dunes.
This would take me way too long to accurately describe. A huge volcanic eruption led to the formation of these dunes. Found a great description online: “Driving up to Great Sand Dunes National Park and Preserve, the view seems almost silly: Across from shallow creeks at the base of the 14,000-foot Sangre de Cristo Mountains sit the largest sand piles in North America, kept in place by wind and water.
Melting snow, mountain creeks and storms regularly flush sand down the western side of the mountains, and southwesterly winds push the sand back on itself.
It’s a cycle that has created dunes up to 750 feet high, with sweeping views of mountains and sky.” – NBC News Article by Catherine Tsai
