At one of these super scaled up massive rock outcroppings and jackhammering these things really has a lot of them just falling through the ground. Not sure if it is the scale and their orientation allowing them to dip below the ground level layer or what, but for all the other rocks that have fallen through the world on normal jackhammering, the amounts here are amazingly high.
