The water settles on the basin floor at its cheapest issue, called Lake Lucero. When climatic conditions are optimal, the drinking water evaporates, plus the dissolved minerals recrystallize and form selenite crystals. Selenite could be the crystalline form of gypsum. These crystals are really brittle and fragile. Selenite can kind substantial crystals—some as large as bicycle tires! Visitors to your park can see selenite crystals on hikes to Lake Lucero.
