Enhance your afternoon with quick insights into the geologic story of Grand Canyon at our “Geology Talk” ranger program – presented daily at 2:30 pm. Meet in front of Yavapai Geology Museum. Learn how this immense canyon formed and the science behind the landscape. The program is 30 minutes long and is accessible.

• Grand Canyon is one-mile deep, up to 18 miles wide, 277 river miles long, and displays more than 20 layers of rock The layers tell stories of oceans, deserts, mountains, and swamps that were once here, brought into existence, then swept away over the vast expanse of time.

• Grand Canyon is a geologically young landscape being sculpted from very old rocks. Knowing some of the stories encoded in the rock layers enriches your understanding of our planet and enhances your experience at Grand Canyon.

The program is free of charge. Children must be accompanied by an adult.  The Geology Talk is subject to cancellation, or may be moved indoors due to inclement weather or when lightning danger is present.
