I don't think the sisters know anything about what treasures may or may not be on the property. They dynamited one cave to keep people out that had carvings on the ceiling but if you know where it's at then you can still get in through the rubble. There are several treasure related carvings on the property and they are in different locations meaning different caches. It would be my guess that at least a few of those caches are still there and, based on where the carvings are located and how spread out they are, there ae several the sisters didn't know about to begin with. There's other things with the sisters and the sale of the land that I am not at liberty to discuss that would also make me believe they don't have any idea what may or may not be there.
It would also be my opinion that nothing was moved from one spot to another. If they recovered it they spent it and most if not all of these caches would have been put down after the Civil War so you would be talking about them putting them in the ground one year and just a year or two later moving them. There are too many markings on the property for that to have happened. I think whatever they put there stayed there unless they came back themselves to recover and spend it.
