The Green River cut this gorge through the Uinta mountains and exposed high cliffs that show geologic formations dating back 300 million years. They have signs along the road that say dinosaurs lived here, coal was found here, Jurassic period, crustaceous period……They seem pretty serious about their geology around here. There is a geology drive and there are a number of fossil digs in this general area too. It does seem pretty amazing to be standing next to rock that formed so long ago. It is beautiful too. There is lots of color and wild looking erosion formations. It has been a good stop but we are heading on tomorrow to one of those fossil digs, Dinosaur National Monument.
