Geology Trail Professional Guide
Detailed Trail Description from our Guidebook
"Because this hike is mostly downhill, it is an easy hike. We say mostly downhill, but there are places involving a bit of rock scrambling if the ranger leading the hike that day wishes to point out some still-imbedded dinosaur bones. For most the hike would be meaningless unless you joined one of the scheduled interpretive walks with a park ranger. In fact, in the interest of preserving Dinosaur’s fossils, the park discourages individuals from striking out alone.
But make this hike you should, for the short hike descends through six geological formations—meaning that when you reach the bottom, you will have hiked through eighty million years of time. The formation is a repository of gastropods and other marine organisms. It is also the area in which our ranger/naturalist guide showed us petrified wood. When you realize these fossils existed during the time dinosaurs roamed the area, you understand what an incredible sight you are seeing. Also present in the Morrison Formation was chert, a dark rock used by Indians for making arrowheads."
