Tuna Canyon lies about 1.5 miles northeast of the Scorpion Ridge landform on the Colorado River.

The east flank is bordered by the massifs of Mencius Temple (South Tuna Canyon), connected to Confucius Temple, northeast, and connected north with Grama Point, (Northeast Tuna Canyon).

(Grama Point also overlooks South Crystal Canyon, the extensive north tributary of the a Colorado River, to the east.)

The Tuna Canyon, valley floor has a gentler sloping geology, from the dramatic cliffs, of the points to the north, and the massifs of Mencius and Confucius Temples at the east and northeast.

The upper platform of the Redwall is omnipresent in the canyon, supporting numerous named landforms.
