There's sand dunes and then there's The Sand Dune

On the way back from Mirador we have a full frontal view of Cerro Blanco, the highest sand dune in the world. It's a whopping 3875 ft from base to summit, that's higher than England's highest mountain. The picture from my phone can't do it justice, it really is almost unbelievably huge for plain old sand..
