In the US state of New Mexico, this amazing and unusual area stretches for almost 700 km². It is unlikely that somewhere on the planet, except, of course, snow-covered latitudes of Antarctica, there is such a strange vast space of barkhans, ridges, high hills sparkling in the sun with crystal-snowy overflows … If it were not for scorching heat … The Desert of White Sands. Indians-Apaches and European immigrants aptly called it “porcelain.”
In fact, such an outlandish landscape-sand phenomenon of the desert is due to the gypsum crystals, and not quartz grains like in any other similar natural zone. And snow-white variety of gypsum – soft selenite, similar to chalk. In particular, the cover of the albino desert is precisely selenite. Once, here, instead of sand was a shallow sea. The interaction of the sun and the sea, geological processes, wind and water erosion have done their job. Meanwhile, ridge, sandy selenite sandstones at the foot of the Sacramento are about 18 m high. Striking, with unusual “two-story dunes” slowly moving in the north-west direction. The width of the moving barkhans is 8 km, and the length is about forty km.
