Harpers Corner Road is closed from the first significant snowfall some time in December to approximately Easter.
Most dirt roads in the park are clay based and impassable when wet, even with four-wheel drive vehicles including the roads to Echo Park, the Yampa Bench Road, and Island Park Road. These roads are not maintained in the winter and can be impassable due to snow.

Do you know the difference between a petroglyph (pictured here) and a pictograph? Petroglyphs are images pecked into rock while pictographs are painted images. Dinosaur National Monument preserves both forms of Native American rock art.
