One of the wonders of the world is White Sands National Monument. The famous dunes encompass 275 square miles of desert and is the world's largest gypsum dunefield. . The pure gypsum that forms these unusual dunes originate from an ephemeral lake or playa with a very high mineral content. As the water evaporate, the minerals are left behind to form gypsum deposits that eventually are wind-transported to form these white sand dunes.
We first stopped at the very nice Visitor Center. As we started driving through the park, we remarked it was like driving through the mountains after a snowfall.
Some species of plants can survive burial by a moving dune by a process called "stem elongation." As the sand rises, the plants quickly grow upward to keep their leaves above the rising sand .
A fascinating place and we enjoyed ourselves very much. Our timing was good as the next day was windy and wouldn't have been much fun with sand blowing everywhere. Sunday we leave for Brantley Lake, the next leg of our New Mexico adventure.
