What are the coordinates for the ruins on endless ocean

I don't know the co-ordinates, but if you look around Knives Reef and head down the map, you might come to a deep cut in the rocks. If you can't see round the corner, then you are there! It is awesome, you can go into rooms and decipher the stones. But you have the wait for that. And if you go to the furthest side, you'll see stone heads with faces. Go behind those and you'll find the whale beads. I hope I helped!
