We were digging a well in the yellow area and the shaft felt down, so we insert a video cam in the hole and we saw an old stone wall at about 4 meters depth thats why i'm trying to see if there's a buried objects down there.
i'm getting gold sealed either in pots are glass jars,the same place Art pointed out, your spot with circle showed to lead to art spot with tunnel's..green dot shows seal cave,with the tunnel's.
I have 2 deeper anomalies, at the 2 red line rectangles. The top one seems to have some loose coins down to about 7-8 ft depth. This might not be a buried treasure, since it was like loose coin signals. The red circles are surface coins or only down to 1-2 ft depth, a place you could check metal detecting for loose or scattered coins/treasure. That's all I have for the moment.
Green in general is a color indicator, I use for various other targets mostly archaeological (old ruins or foundations but especially those non-metallic objects such as Indian flints, glass, pottery, carved stone with treasure signs).
