The Bone Pits were a cave network riddled with wampas, located within the Tromper Crags of the planet Hoth. Access to these pits was gained through a tunnel opening onto Icefinger Rise. During the era of the Cold War, the White Maw pirates built a base that linked to these tunnels. Consequently, Cipher Nine exploited the walls to eavesdrop on a clandestine meeting involving the Marauders and the operatives of Admiral Layek Davos.
