Going to the Grand Canyon

Written By Allen Glazner

I’m headed to the Grand Canyon in May to go on a rafting trip led by Wayne Ranney for Colorado River & Trail Expeditions, and then to help lead a National Geographic trip to Grand Canyon, Bryce Canyon, and Zion National Parks. As my memory for stratigraphic sections has never been all that good, I’ve prepared simplified a stratigraphic column for Grand Canyon National Park and another for the region of Utah surrounding Bryce Canyon and Zion National Parks. These have been taken from a number of great sources that are cited on the figures.

I hope others find these useful when visiting the areas. Download the columns from this page.
