Coral Pink Sand Dunes State Park

You've probably heard of the red rocks in Sedona, but there are red rocks all over the Colorado Plateau.  In this particular place, there is a gap in the mountains, and over the centuries, the wind has eroded the red cliffs, picking off grains of sand and carrying them into the valley.  In the gap, because it is narrow, the wind velocity is high, and in the valley it slows down (venturi effect) and the sand falls to the earth at Coral Pink Sand Dunes State Park, near Kanab, UT, and forms large dunes.

You can hike the dunes (we did), or use ATVs on one section.  There are animals there, we found some tracks
