It has nothing on Verona Rupes on the Uraniun moon, Miranda, which is over six miles high, but it's still pretty cool.

Olympus Mons is an enormous shield volcano on the planet Mars.
The volcano has a height of over 21.9 km (13.6 mi or 72,000 ft)as measured by the Mars Orbiter Laser Altimeter (MOLA).

I see what you did there.
You said Uranian, because you didn't want Uranus, moon and Miranda in the same sentence, because you knew where this thread woul go.
Someone would say "Hey Laz, Miranda saw Uranus when you mooned her!"
But your fears are unfounded.
We're not like that here. (SNORT...GUFFAW 🤪🤣ðŸ¤)
