GRAND TETON NATIONAL PARK, Wyo. — As the National Park Service celebrates its 100th birthday by allowing people to visit all of the nation’s national parks for free through Sunday, the south entrance to Yellowstone is closed.

The 12,000-acre Berry Fire in Grand Teton National Park started a month ago during a lightning storm. It had rapid growth early this week as a result of dry, windy and warm conditions.

Highway 89 is closed. It serves as the south entrance to America’s oldest national park, Yellowstone. Fire managers expect the closure to remain at least through the weekend.

Popular tourist areas in Grand Teton and Yellowstone are open for the celebration of the park service’s centennial.

The fire became very intense earlier this week.
