The Bone Pits was a wampa-infested cave system in the Tromper Crags on the planet Hoth, accessible via a tunnel that opened onto Icefinger Rise. By the Cold War, the White Maw pirates established a base which connected to the tunnels. This led to Cipher Nine tapping into the walls in order to spy on a meeting between the Marauders and Admiral Layek Davos's agents.
