Wow. Who said there’s nothing big left to discover on Earth?: [http://www.cnn.com/2013/08/29/world/europe/greenland-megacanyon/index.html?hpt=hp\_t5](http://www.cnn.com/2013/08/29/world/europe/greenland-megacanyon/index.html?hpt=hp_t5)

Cool. I flew over Greenland a few years ago and was in awe of all the stark features (glaciers, huge rivers of ice, rocky terrain with no vegetation, etc.)
