DINOSAUR | Superintendent Mary Risser announced that Dinosaur National Monument’s Harpers Corner Road, which begins two miles east of Dinosaur, Colorado, on US 40 and runs 31 miles north into the monument, was closed to the public on Jan. 1, 2010. The first five miles of the road up to Plug Hat Butte will remain open and plowed throughout the winter to allow public access to the Plug Hat parking area for snowmobile and cross-country ski enthusiasts.
Cross-country skiing and snowmobile use are allowed on the closed portion of the road beyond Plug Hat Butte. Snowmobiles are not allowed off the road surface and may not go past the Echo Park Road turn-off 21 miles north of Highway 40.
The Split Mountain campground on the Utah side of the Monument will remain open for the entire winter. The campgrounds at Rainbow Park, Deerlodge, and Echo Park remain open, but snowfall may prevent access to those
campgrounds as the winter season progresses. Campgrounds have vault toilets but no running water. No fees are charged at these campgrounds during the winter season.
