The Grand Canyon is one of the oldest natural landmarks on Earth. Researchers estimate that the Colorado River started carving out most of what we now call “The Grand Canyon” around 5 to 6 million years ago. Others found evidence that its formation could have started 17 million years and a smaller handful found information that could point its initial creation to 70 million years ago.
One thing that’s for certain is that dinosaurs haven’t seen the Grand Canyon, at least not the one we currently enjoy today. Scientists at Arizona State University analyzed the topography of the land and their results found that the walls of the Canyon eroded extremely quickly, younger than 6 million years. This means that the dinosaurs came and went before the canyon came to be. For further details on this finding, click here:: Dinosaurs (Probably) Never Saw the Grand Canyon
