So we drift another 3 meters forward and we found a pile of stones; 1.5 meter in length, 12 inches or more in width, and 1.5 meter high. At the back of the pile of stones, we found a rock; it was like an open book in a sliding form. So we continued digging for another 1 meter and went down 1 meter distance. We found another 3 rocks as big as a coconut laid in a triangle form. It was under the water.
We need advice regarding this one. Hope you help us.
We cannot show you a picture of the site. So we tried to draw how it looks like.
Here it is.
