The view in this panorama coincidentally lines up Shinumo Altar with Nautiloid Canyon just below it and a bit to the left. Nautiloid Canyon is relatively short in length. From its break in the canyon wall at a large pour over, to its intersection with the Colorado River, the distance is a mere 1.25 miles as it drops nearly 2,500’ from the rim to the river. Many river raft trips stop at Nautiloid Canyon for a short scramble up the wide slot canyon to view the large Nautiloid fossils embedded in the rock. The reason I named this panorama Eminence Break in the nadir cap, however, is because of its view, albeit faint, of the geological fault called Eminence Break. Zoom far into the panorama towards Shinumo Altar. In front of the Altar you will be able to see a long line of low bluffs colored a lighter tan or gray. They stretch from left to right in this view. The shadows at the right end of the bluffs make them more visible where they emerge from behind the near-side cliffs of Marble Canyon. The Eminence Break stretches in a nearly straight line for a distance of 15 miles, from the Marble Canyon wall almost to Bitter Springs, AZ at the base of the Echo Cliffs.
