Old Gullet sinkhole

The Old Gullet sinkhole is a location in the Commonwealth

Background
The Old Gullet sinkhole is a giant crater-like hole that formed in Malden when a former neighborhood was swallowed by a sinkhole that formed sometime after the Great War. The sinkhole destroyed most of Malden north of Malden Middle School and west of Greentop Nursery.

Layout
The Old Gullet sinkhole now only contains a single deathclaw near the center. A river flowing down into the crater leads to a cavern underneath the sinkhole, serving as the only entrance to the cave upon initial discovery. Inside, the corpse of a brahmin and three dead raiders (one is partially obscured underneath the falling water) can be seen, along with a fair number of radroaches and the remains of Grandpa Savoldi. The only exit will take the Sole Survivor past a small pack of feral ghouls.

Exiting via this path will lead the player character to the interior of a house just west of the sinkhole. As the door is chained, it is only accessible through the cave or via a jet pack. A group of Super Mutants or a pack of mongrels may be waiting outside the house.

Loot

 * Vault-Tec lunchbox - In the broken pipe without water flow.
 * Wasteland Survival Guide issue #7 - In the cave, on top of the cooking station.
 * Grandpa Savoldi's hat - In the cave, next to the skeleton by the cooking station. Only available during the miscellaneous quest Fallen Hero.
 * Sleepwalking note - In the house where the player character exits the cave, on the top floor inside the chem cooler to the right of the bed.

Bugs
The deathclaw at the bottom of the sinkhole may not attack the player. If engaged, it will start attacking, but will otherwise sit and do nothing besides watch the player. It will, however, attack other creatures in the area.
