The Grand Canyon
The Grand Canyon has been a place where many different stories have centered, and while Allan’s discovery does add to its appeal, these stories have been circulating long before the stone was found. The history of this place is almost two billion years old.
Becoming the Grand Canyon
When the Grand Canyon was forming, soaring temperatures and comprehensive forces caused the igneous and metamorphic rocks to form. After this, sedimentary layers were created. However, the ravine only took shape around 65 million years ago.
