There are unusual features under the water just off the coast of Cape Town, South Africa. A 3 mile wide platform that stretches for over 37 miles in bisected by another strange feature that cuts into the ocean terrain.
What could have caused these features to form. Is it natural or man-made. Something constructed before the sea levels rose or are they structures that are currently being used by an alien civilization that has existed in our oceans for thousands of years.
The ocean has many powerful moving currents, so if these are paths created by ships with sonar, how were they able to maintain such straight lines?
