As I stated previously, we are seeing a lot of national monuments these days because there are a lot of them here in the Southwest. Most have to do with Native Americans having been here and feature hundreds-of-years-old remnants of their time in a particular place. But not this national monument. White Sands NM has nothing to do with former tribal locations, rather it features a very cool natural wonder — glistening wave-like dunes of gypsum sand covering some 275 square miles of desert here in southern New Mexico.
I could get into a long scientific explanation of what created this rare form of sand, but I’ll just summarize that gypsum in the mountains, carried down to a basin with the rains, then blown and broken up into small sand-sized pieces is what forms these brilliantly white dunes. They’re spectacular and really other-worldly! Have a look at what we enjoyed at White Sands National Monument.
