Denver (AP) The U.S. forest service says 23 campgrounds and picnic areas in northern Colorado and southeastern Wyoming will be closed for the season because of hazards caused by trees that have been killed by bark beetles.
Another 17 campgrounds across three national forests won't be opened until later in the summer. Forest service officials say trees killed by bark beetles pose a hazard because they can fall as the roots start to rot.
The forest service is also treating and cutting trees in some of the campgrounds.
Bark beetles have killed huge swaths of pine trees in Colorado, Wyoming and South Dakota. The bugs that burrow under the bark have killed about 1.5 million acres of trees in Colorado.
