Different Past World Hides Under Sand Dunes

Did you know

I love unusual journeys: to the depth of the ocean, to the core of planet Earth. This time it’s gonna be a journey to the world’s biggest sand dune! I’d like to explore what’s hidden underneath it: maybe there’s a secret forest inside or an ancient city. Are those just huge piles of sand or something unique is hidden in those layers? Are you ready to join me?
