Nature is incredibly resilient. This twig-thin stalk of soaptree yucca manages to grow across the 115 square miles of drifting dunes in White Sands National Monument, New Mexico. This park in the Tularosa Basin is covered with selenite crystals or gypsum. The snow-white material is constantly blowing while creating unique sculptures and wind-swept ridges, knolls and enormous hills. This region averages 100 days with heat above 90° F. Yet the dunes remain cool while snowplows are constantly clearing the road of gypsum sand.
