Once a Garrahan Mining Company mineshaft, now the caves are filled with makeshift buildings alongside contraptions such as automated turrets and a machine-powered shotgun. Such constructs were built by Lou in an attempt to end his life, as he could not bring himself to pull the trigger himself.
It can be found directly under the butterfly on the world map. The mine is accessible by a cave entrance leading to a long narrow tunnel. This abruptly stops at a large metal door locked by a terminal. There is a short tunnel to the right that leads to a dead-end, though the path is cleared during the quest Cheating Death. During the quest, a deep, intricate series of caves and tunnels are revealed, consisting of radscorpions and mole miners.
