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 (Fallout 4) den containing one deathclaw. There is a river flowing down, and then into the sinkhole. This is the only entrance to the lower cavern. By jumping in, you are transported to a cavern below, that contains the corpse of a Brahmin and a couple of dead raiders. There's good loot down there, as well as a fair number of Radroach (Fallout 4) including one Glowing Radroach. The only exit will take you past a small pack of Feral ghoul (Fallout 4) and a Glowing one (Fallout4).

Exiting via this path will lead you to the interior of a house just west of the sinkhole. The house you exit through has a red door that is barred with chains from the inside, and is only accessible through the sinkhole. But don't leave just yet! There's a lot of good loot on the top floor. Go up the staircase.

Notable Loot
