(CNN)A 7-year-old girl from Georgia camping with her family in Great Smoky Mountains National Park was killed Wednesday when a tree fell on their campsite, park officials said.
Rangers responded to an emergency call at the Elkmont Campground in Tennessee at 12:30 a.m. Wednesday, the park said in a news release.
A large red maple tree that was about 2 feet in diameter fell on the family's tent, the release said. The girl's father and two siblings were not injured.
The park closed the campsite and adjacent campsites as a precaution, officials said.
Great Smoky Mountains National Park spans the border between North Carolina and Tennessee. It's known for its diversity in plant and animal life, and is the country's most-visited national park, according to its website.
