Just off the southwestern corner of Mauritius (shown at the center of this Overview) is what appears to be an underwater waterfall.

Mauritius is an island nation in the Indian Ocean, roughly 1,200 miles (2,000 km) off the southeastern coast of Africa.

Griend is a small, uninhabited Dutch island located in the Wadden Sea, roughly 62 miles (100 km) northwest of Amsterdam.
