However, the largest volcano on the planet, Olympus Mons, is thought to have formed when the plates were not moving. Olympus Mons may have formed just after the plate motion stopped. The mare-like plains on Mars are roughly 3 to 3.5 billion years old. [72] The giant shield volcanoes are younger, formed between 1 and 2 billion years ago.

If it feels like your week has been dragging on forever, consider this — a volcano on Mars once erupted for 2 billion years straight, which is nearly half of the planet's 4.5 billion-year lifetime.
