Yes, there are nautiloid fossils exposed in the limestone floor of Nautiloid Canyon. This is one of them. It's probably just a little larger than my computer keyboard. Their shells were chambered and they now show up well. This is at mile 35, just a little above Redwall Cavern.

This is a difficult subject to photograph. It required use of the LAB color space in Adobe Photoshop to obtain decent contrast.

But the real highlight of Nautiloid Canyon, in my opinion, is looking up right above the fossils. It's a short, tight canyon with several large rocks that have crashed over the fall. This is obviously not where you want to be during a flash flood. You have to climb up a ledge to get here.
