A previously unknown central canyon hidden beneath two kilometres of ice covering Greenland has been discovered by a group of paleo mega scientists, led by a team from the University canyon of Bristol.

A 750km canyon preserved under the ice for millions of years is a breathtaking find in itself, but this research is also important in furthering our understanding of Greenland' s past.
