Olympus Mons. It's the largest volcano in the solar system. It's been erupting since the Omegas terraformed Mars. Nobody seems to care. 
Located on Planet Arakko, Olympus Mons was the largest volcano in the solar system.[1]
History
Following the terraforming of Mars, Olympus Mons began erupting. The continued eruptions caused a gigaton of dust to create a storm that followed the moon Phobos ("like a puppy").[1]
With a gateway seed planted in his brain, Legion went to the top of Olympus Mons and began meditating with Xorn and Zorn protecting him. After 63 mutants were killed at the Green Lagoon, Professor X confronted Legion on Olympus Mons.[2]
The mountain would eventually become part of the domain of Isca the Unbeaten, following her retirement from the Great Ring of Arakko. Isca guarded her solitude carefully, and when civil war broke out on Arakko, she killed anyone who crossed her lands.[3]See Also
