well first off its not a vault of big rock, etc. he says they excavated a hole/vault about 6 ft down LINED with flat rock,they found around the area, secured the pots on top/with wire. etc then covered back back with rock and dirt. this is not a cave nor a rock hollowed out. they built it... I found article said they arrived at goose creek follow a trail that parrelled the creek. came to a pass close to peaks of otters, and looked around the pass and found a place. its in one of the gaps close to the peaks... but they are a lot of them..
