Rock pile excavations

Back in the Wild West event I crafted a lot of rock piles to decorate the various “natural” areas such as the desert and the national park. I thought they’d look good in the zoo also - but I’d used them all. Finally I remembered that one of the loot prizes in the excavation area from the prehistoric event is one of the rock piles. I’ve had to dig up a lot of old washing machines, barrels and Stonecutter walls, but I finally have enough new rock piles that I think will go well in the great plains area :)
