Where on Earth?

A diver examines the wall of a Byzantine structure, measuring 30 by 30 meters (almost 100 by 100 feet), beneath the waves east of Canopus in Abu Qir Bay, Egypt. This settlement became submerged probably in the 7th century, due to a climate change event that caused high floods on the Nile River. Over the last 8,000 years, changes in the Nile have shaped civilization in Egypt. Read story on page 22.
