Black Rock Quarry Hidden Location. I cant find anything to do with this hidden area it is located to the immediate left of the black rock quarry entrance where you go down a slight hill and run into a forklift parked into a wall you can blow up the forklift to destroy some of the wall and then continue to break the wall. Hidden Location 7 Black Rock Quarry 326 When you first enter the Quarry look for a path to your left seeming blocked by large cubes.
In the entrance area of the black rock quarry there is a hole between some rocks that leads to an area infested with mold. Levitate through the hole or launch a forklift to blow the wall. Theres an entry point in the top right.
Use it to take the elevator up.
