Mohole
From Kerbal Space Program Wiki
Moholes are deep holes on the surface of Moho. The only two currently known are at Moho's geographic north and south poles.
They may be named after one or more of the following things:
- They are holes on Moho, so they are called "Moholes"
- They may be named after a deep well called the "Mohole" in Red Faction: Guerrilla
- They may be a reference to Project:Mohole
