Colorado's Great Sand Dunes National Park is home to the tallest sand dunes in North America. It's this considerable height that makes them perfect for sandboarding. And its remote location means Great Sand Dunes National Park at night is an absolute treat.

But how did they get that way? Why are the Great Sand Dune so tall?

This video sets out to answer that question and more. Because the dune system is so complex and relies on so many factors to achieve its great height, it means more than just the dunes themselves need to be protected.

So, answering the question of "Why Colorado's Great Sand Dunes are So Tall?" really lets us get at the heart of why the dunes are so worthy of protection in the first place and shows us the interconnectedness and complexity of one of the world's great sand regions. I hope you enjoy it.
