There are 5 National Monuments in Colorado
(if I am missing any please let me know)
1. Colorado National Monument in Fruita, Colorado
The website states: Colorado National Monument preserves one of the grand landscapes of the American West. But this treasure is much more than a monument. Towering monoliths exist within a vast plateau and canyon panorama. You can experience sheer-walled, red rock canyons along the twists and turns of Rim Rock Drive, where you may spy bighorn sheep and soaring eagles.
2 Dinosaur National Monument in Dinosaur, Colorado
As the website states: Dinosaurs once roamed here. Their fantastic remains are still visible embedded in the rocks. Today, the mountains, desert and untamed rivers flowing in deep canyons, support an array of life. Petroglyphs hint at earlier cultures. Later, homesteaders and outlaws found refuge here. Whether your passion is science, adventure, history or scenery, Dinosaur offers much to explore.
3. Florissant Fossil Beds National Monument in Florissant, Colorado
As the website states: Beneath a grassy mountain valley in central Colorado lies one of the richest and most diverse fossil deposits in the world. Petrified redwood stumps up to 14 feet wide and thousands of detailed fossils of insects and plants reveal the story of a very different, prehistoric Colorado.
4. Hovenweep National Monument in Cortez, Colorado
As the website states: Once home to over 2,500 people, Hovenweep includes six prehistoric villages built between A.D. 1200 and 1300. Explore a variety of structures, including multistory towers perched on canyon rims and balanced on boulders. The construction and attention to detail will leave you marveling at the skill and motivation of the builders.
5. Yucca House National Monument in Mesa Verde, Colorado
As the website states: Through a continuing tradition of public and private cooperation, Yucca House National Monument preserves one of the largest archeological sites in SW Colorado. The unexcavated nature of the site preserves its integrity and beauty for future generations of scientists and visitors. Experience a sense of discovery by visiting a site that has remained largely untouched for the past 800 years!
Have you ever visited a National Monument? We visited Craters of the Moon National Monument in Arco, Idaho and it was absolutely amazing. They say it is the closet experience you will have to walking on the moon.
