I always wonder what's under sand dunes
I spent a long time looking at this photo of a sandy desert (?the Atacama?) somewhere in Chile. Whenever I see sand dunes, I start to wonder what might be underneath them. Dunes move, and in so doing can bury anything in their path. I remember reading stories* about Hollywood movie sets abandoned decades ago now emerging as the California desert dunes that covered them up now move onward. When glaciers retreat, archaeologists find well-preserved artifacts from prehistoric times.
What's under these dunes? Remnants of old cities? Burial sites? Fire rings? Fossils? Diamonds? Alien artifacts? Sandworms?
