There is a flooded quarry surrounded on all sides by straight-up rock walls. The breaks in the wall are a ramp on the western side and an embankment on the north and southeast corners. At the end of the ramp are some portable toilets and some explosives. One of the toilets contains a cat bowl and a Mr. Fuzzy yellow hard hat. A mirelurk queen lurks beneath the surface of the water and will attack if disturbed.
