When an avalanche happens at the Great Sand Dunes in Colorado, it sounds like the sand is singing. Huh? How? Why? We learn about the special sand and the specific conditions that make this acoustic phenomenon possible. This is the third of five episodes looking at some of the coolest science happening at our National Parks.
