The location consists of two buildings and a refinery laid out north to south. The easternmost building has a cooking station up at its north end, and two dumpsters are along the eastern wall. The western wall has lockers with a potential armor mod inside and a weapons workbench. Inside the building is a mattress. To the west is a refinery.
In the southwest corner is a larger two-story building. Proceeding through the eastern barn door, straight forward is a staircase, to the left is a power armor station. Further in and on the northernmost wall is a tinker's workbench. At the top of the stairs, there is a level 3 safe on the right and an armor workbench to the left. Turn around, there is a bed across a walkway. From there, a northern door opens to the top of the refinery.
Abandoned mine shaft 4 appears only in Fallout 76.
