The dunes exist because of a gap. Wind squeezes through the notch between the Moquith and Moccasin mountains, accelerates, lifts sand off eroding Navajo sandstone, then drops it where the valley opens and the wind slows. The iron oxide in that sandstone is where the coral color comes from. Two things to know before you go: roughly 90 percent of the dune field is open to ATVs, so quiet is not the draw, and the Coral Pink tiger beetle living in this sand is found nowhere else on earth.
