The Dinosaur Ridge Trail (W. Alameda Parkway)
This 1.5-mile trail along Alameda Parkway, between Rooney Road North and County Road 93 (see map), has hundreds of dinosaur tracks, a quarry of dinosaur bones, and interesting geologic features. To hike the Ridge will take between 1-2 hours and is about 2 miles round trip.
Built by the City of Denver and maintained by the Friends of Dinosaur Ridge, West Alameda Parkway traverses the Dakota Hogback, which has locally been renamed “Dinosaur Ridge” by the USGS. The National Park Service has designated the area a National Natural Landmark, the state of Colorado has made it a Colorado Natural Area, and the Colorado Geological Survey recommends it as an official Point of Geologic Interest.
The trail has over 15 sites, each marked by an interpretive sign. Fossil sites, interesting rock sites, and scenic overlooks provide hints to the prehistory of Colorado’s Front Range.
The Dinosaur Ridge Bone Quarry
Quarry Number 5 is the Dinosaur Ridge Bone Quarry, and was the site where the world’s first Stegosaurus was discovered. Several vertebrae, parts of limbs and pieces of the famous plates were uncovered and can now be seen on display at the Morrison Natural History Museum (see their link on the Contact Us section).
The bones exposed today at our interpretive site are most likely from Stegosaurus and Apatosaurus and washed into this small braided stream channel deposit likely during a rainy season flooding event. Our Bone Quarry is one of only a few locations where you can see and touch dinosaur bones in the rock where they fossilized long ago.
