The Denver of 100 million years ago looked very different than today. It was a beach along which herds of iguanadon dinosaurs migrated. These tracks are at Denver’s Dinosaur Ridge National Natural Landmark. A number of similar (but less impressive) trackways have been found stretching from Boulder to northeast New Mexico, causing famed dinosaur tracker Martin Lockley to call this the “Dinosaur Freeway”.
