Grand Canyon May Have Already Existed in Age of Dinosaurs

Geologists, who have been fighting about the Grand Canyon’s age, now have evidence that suggests the bottom of one of the world’s most famous gorges is about 65 million years older than thought.

Scientists from the California Institute of Technology and the University of Colorado at Boulder found data that may point to the formation being carved to near its modern depth 70 million years ago. That would date the canyon to the Late Cretaceous period when Tyrannosaurus Rex still roamed the earth before their demise about 5 million years later, according to a study published in the journal Science.
