This article is about how some carvings in the Grand Canyon
date back to 60 million years ago. Back to when the dinosaurs still roamed the
Earth. This is pretty cool because now that we know the Grand Canyon is 60 million
years old in some places, we can also figure out how old other things are by
comparing the two. For example, we could look at some markings in the Grand
Canyon and compare them to the carvings inside a crater and figure out how old
the crater is.
I liked this article because it talked about how old the Grand Canyon is and that is something I have always wondered. I have also been to the Grand Canyon and this article brings back memories from being there with my family. When I read the article I thought ‘If the canyon was here when dinosaurs were alive did some dinosaurs live in it? Why wasn’t there proof before?’
