Old Gullet sinkhole

The Old Gullet sinkhole is a location in the Commonwealth in Fallout 4.

Layout
The Old Gullet sinkhole is a large crater in a former neighborhood that, as the name suggests, has begun to swallow up the surrounding buildings, many of which have collapsed in. At the bottom is a Deathclaw. There is a river flowing down, and then into the sinkhole. This is the only entrance to the lower cavern. By jumping in, the Sole Survivor is transported to a cavern below that contains the corpse of a Brahmin and three dead raiders (one is partially obscured underneath the falling water). There's a fair number of radroaches. 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. The house that the player character exits through has a red door that is barred with chains from the inside, and is only accessible through the sinkhole.

Notable loot

 * Wasteland Survival Guide down in the cavern next to the cooking station.
 * Sleepwalking note in the chem cooler to the right of the bed, top floor in the house where the player character exits the Sinkhole
 * Grandpa Savoldi's hat Used for miscellaneous quest. skeleton by cooking station.

Appearances
The Old Gullet sinkhole only appears in Fallout 4.

Bugs
Interestingly, it seems that entering via certain ways can avoid triggering the Deathclaw to attack. Jumping from a high ledge into the pit can lead to the Deathclaw sitting in its spawn location, where it will not attack the player upon detecting them.
