Dinosaur National Monument
Pristine sky, where the Milky Way casts shadows on the ground.
Sitting on the Colorado-Utah border in a remote stretch of canyon country, Dinosaur National Monument holds some of the darkest skies of any certified site in Colorado. Bortle 1 conditions mean the zodiacal light and gegenschein are visible on moonless nights, and the canyon walls block any distant glow on the horizon.
