NASA has found a hidden canyon beneath the surface of Greenland. The "megacanyon" looks about 50% longer than the Grand Canyon in Arizona, but not quite as deep. It looks as though it was created from an extensive river system, and most likely predates the 3-kilometer (1.9 miles) thick ice sheet covering it up. Scientists think that it has been covered up for about 4 million years. The canyon was discovered while people were examining the ice sheets that are hiding it, and is an exciting find that just proves that even while we're living in the 21st century, we're still finding gigantic features hidden underneath the Greenland ice sheet that we never knew about before.
I find this discovery fascinating. I'm awed at how much we still have yet to discover on our planet, even with all the technology we have today. It keeps things interesting. It's truly amazing how much the earth can hide for so many centuries, no matter how much more we think there could be for us to find.

Did this set the record for the longest canyon, and do you think this will aid in other scientific discoveries in Greenland?
ReplyDeleteI love how nature can hide in the most obvious places. :D
