I was able to pull out from the cliff face a whole, but misshapen small green bottle approx 6" x 2" It is a screw top (it even has the cap and had some liquid in it)! It has been melted but remains intact (making it look really cool). This area was once a landfill and the cliff erosion covered up these old bottles. On the bottom, it has the number 6 in the center circles (carved into the glass) and what looks like RP2 (?) in the bottom right of the circle.. . any thoughts?
