Younger Grand Canyon age confirmed

A new report in Geology by Karl Karlstrom and colleagues, refutes the claim that the Grand Canyon starting forming 17 million years ago. The article, "Model for tectonically driven incision of the younger than 6 Ma Grand Canyon," confirms an age closer to the age documented by AZGS geologists Phil Pearthree and Jon Spencer.

  1. My self interest forces me to point out that NBMG geologists Jim Faulds and Kyle House also played a major role in the research that supports a the 'young canyon' model.

    We have a great collaborative effort going between AZGS and NBMG.
