Explaining the “Dragon Bones” NASA Curiosity Found on Mars

Did NASA’s Curiosity rover really find dragon bones on Mars? Well, no. But these awesome-looking formations are a clue to the planet’s fascinating geological history. The likely story behind all of these formations is that they were once deposits of harder material, originally surrounded by softer rock types and sand, back when Gale Crater was a Martian lake. Once the water was gone, over the eons wind erosion slowly wore away the softer stuff and left the harder parts — the spikes, spires and flowers — behind, creating the crazy formations seen by Curiosity. It's not quite as cool an explanation as Martian dragons, but I mean, what would be?
