Nautiloid Canyon

Mile 34.5 - Nautiloid Canyon

This short and steep side canyon is named after the fossils contained within the rocks of the canyon. These conically-shaped nautiloids ranged the world's oceans several hundred million years ago. The fossils are the remnants of distant relatives of the modern day chambered nautilus, squid, and octopus. River runners can view these amazing fossils in the smooth and polished grotto of Nautiloid Canyon. By pouring water onto the limestone floor, distinct shapes emerge, revealing the conical chambers of these prolific sea dwellers.
