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 and some time, you can come back and the whole place is taken by raiders, the water is gone and you got whole new location to explore.

Notable loot

 * Taboo Tattoos - in the metal trailer caravan on the marble edge (south) of the excavation area, close to two other trailers.

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 kneedeep in concrete, Sully always hover around the compressor/pump), before the Sole Survivor suddenly fall 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.
