Site was scanned, positive indication. Then we use another detector, Anderson Rod, EXACT SAME SPOT is pointed to be positive.
Digging started. At 4meters, skull of animal remains found (goat-like skull), then a row of logs more or less 3ft long. Then egg-shaped white stone (no file picture of this stone). At 5meters, black round stone (bigger that a fist) found on top of marmol looking, flat stone as if it is a covering. Notice on picture those broken stone have a flat and smooth side about 2 to 3inches thick. We broke it. Underneath is black fine sand with strong odor. Diggers cannot work under due to the smell. Water now 1meter deep. Any comment/help from you guys will be highly appreciated. Thanks in advance guys.
Presently, that strong odor is gone.
