Dinosaur Ridge is one of the most renowned dinosaur fossil sites in North America, originally excavated in 1877 as part of the major paleontological dig efforts that resulted in the discovery of some of the world's most recognizable dinosaur species today, including the Stegosaurus, Apatosaurus, and Allosaurus. The ridge is located within the Morrison Fossil Area National Natural Landmark in Jefferson County, just outside of the city of Morrison, within the Dakota Hogback natural unit. It has been overseen by the Friends of Dinosaur Ridge nonprofit organization since 1989 and is open to the public for free access throughout the year. Visitors can also explore the lovely Dinosaur Ridge Exhibit Hall at the site and view informational exhibits on dinosaur species uncovered at the site. Interpretive trails offer informational panels detailing the region's geology and paleontology.
