Thicket Excavations

Thicket Excavations is a location appearing in Fallout 4.

Layout
A fenced in quarry area that has been flooded. There are stairways leading up the north side of the quarry and a sloped ramp that extends into the water. The top level on the west side includes an elevator as well as a camper in which Sully Mathis's terminal can be found which details his plans for restoring the quarry for use as a base. There are several campers spread out around the nearby area.

Some time after completing Sully's quest, you may hear that an allied settlement is being attacked by raiders stationed in the Excavations.

After completing the quest Pull the Plug, and some time has passed, the player character can return to the location to find that Sully Mathis has become the leader of a raider gang which he initially commented about doing in his terminal entries.

Notable loot

 * Taboo Tattoos - in the metal trailer caravan on the marble edge (south) of the excavation area, close to two other trailers on the west wall. When standing in front of the pump switch, look directly SW. The trailer you then are looking at is the one.

Appearances
Thicket Excavations only appears in Fallout 4.

Bugs

 * Upon arrival at Thicket Excavation there seems to be a foglike low-res concrete-floor, hovering above most of the real surfaces, and it persists under water. It is the high distance version of the model (aka LOD) you should only see when the object is very far away. This manifests in that both the Sole Survivor and Sully Mathis wade knee deep in concrete, Sully always hovers around the compressor/pump, before the Sole Survivor suddenly falls into the water or access-way leading down into the excavation. The impact of this bug can be negated by restarting the game.
 * If you swim under water to enter the excavation site before draining it, you will fall down to the floor and be able to walk and shoot your gun under water.
 * If you swim around enough before draining the quarry it is possible to cause the quarry to instantaneously empty of water and update the world/quest state such that those enemies appear.
