Dinosaur Ridge Professional Review and Guide
"Long, long before Native Americans, gold miners, or any people at all lived in Colorado, this area was a mangrove swamp populated by dinosaurs. And while you have heard of the Gold Rush, you may not have heard of the “Great Dinosaur Rush” that happened several years later. In both instances, the rush was more of a plunder with natural resources rapidly extracted from these mountains and foothills. What you will see on this walk are footprints, bulges, ripples, and other evidence of that time 150 million years ago that could not be chipped out and hauled away. The signs along the road provide illustrations of what these massive creatures must have looked like when in their native swamp habitat, giving your imagination a few images to work with as you look at the rocks. Brontosaurus (also known as Apatosaurus), Stegosaurus (now the Colorado State fossil), Diplodocus, and Allosaurus were all discovered here in 1877."
