Strange formations at the bottom of the Caribbean Sea off the coast of Costa Rica. It looks like a road or possibly a wall of some kind. It’s 3 miles wide and stands over 2000 feet in some areas.
There is also a huge flat plateau just south of Jamaica that’s over 100 miles long and 30 miles wide. The edges seem to have angular corners that make 90 degree turns.
It could be a natural formation but the overall shapes seems to have been constructed.
