Mohole
From Kerbal Space Program Wiki
The Mohole is a deep hole on the surface of Moho with a depth of 4.6 km. It's located on Moho's North Pole.
Description
It is white on the inside and becomes narrower with increasing depth. The cause of the Mohole is a terrain glitch in the heightmap and until 0.90 it wasn't sure if this will be fixed. With 0.90 the Mohole became a dedicated biome and is thus not so easy to remove without changing the biome maps and science results.
Name
Until 0.90 there was no official name for this feature and the name Mohole devised by the community. So it's complicated to get the real origin for that name but it 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
