Stop 12 at Barringer

Where am I on the tour map?

As we head down the Caretaker Trail, there are some excellent examples of the structure of Barringer Crater, including the overturned rim and a large tear fault.

As at Stop 2, the Kaibab and Moenkopi formations have been uplifted, peeled back, and redeposited on top of each other.

Slightly further down the trail, we can see one of the many large tear faults that occupy each of the four corners of the crater which give it its squarish rim shape. As the rim was being overturned, the tear faults formed along fractures called joints that existed in the rocks before the formation of Barringer Crater. On the left side the fault in the above photo, the rocks were uplifted more than on the right side.
