But, Mazz, it doesn't sound like much is there.
In searching for info I found one reference as follows "a number of low mounds crudely made from local limestone and a network of stone walls" and in another Thomas Gann wrote in 1926 "Several burial mounds were excavated, in which bones were disturbed, the skeletons lying on their backs... and food offerings in pottery receptacles provided for their journey into the next world, indicating the usual method of burial among these people. A second mound was excavated, which had been built over the ruins of a small stone chamber. Nothing was found within it, but beneath the center was discovered a round saucer for burning incense, with a long handle, and a curious figurine in clay, whose face was covered by a peculiar grilled arrangement, more resembling a baseball mask than anything else, which was studded with rosettes."
Do you think this is the same mounds?
