What if a volcano grew for billions of years, unchecked?
On Earth, volcanoes get cut off. A tectonic plate shifts, the hot spot moves on, and growth stops. Mars never had that problem. No shifting plates, lower gravity — nothing to interrupt the build. So Olympus Mons just kept going. It rose to around 22 kilometres — roughly two and a half times the height of Everest. Its base stretches about 600 kilometres across, wide enough to swallow an entire country. And it didn't explode its way up. Runny lava, slow and patient, piled layer upon layer over billions of years — a shield volcano on a planetary scale. The whole thing is so wide that standing on its slopes, you wouldn't even know you were on a volcano. The curvature of Mars would hide it. Follow Deep Field Vault for more like this.
