How Old is the Grand Canyon?

The Grand Canyon is perhaps the most recognizable landform on planet Earth, yet specific details about its formation and age are elusive. It is not for a lack of trying but rather that the canyon was formed by erosion so that much of its earliest history is gone or remains hidden within its stubborn rocks. Recent research into the canyons’ origin has revealed some surprising results which will be shared with listeners in this slide illustrated presentation.

This presentation is free and open to the public.

The event will take place in Garner Auditorium at the W.A. Franke College of Business, Northern Arizona University Campus. Free parking is on East McConnell Drive. The auditorium access is via the west entrance of the College, see map below.
