One of the entrances to Yellowstone National Park has been closed, because of a fire burning in neighboring Grand Teton National Park.

YNP officials say the South Entrance to the park has been closed in both directions, because of the Berry Fire which is burning in Grand Teton National Park, about 19 miles northwest of Moran Junction.

Although the fire is a distance away from the South entrance itself, the fire is threatening the area of highway between Leeks Marina and the South entrance, thus the road has been closed.

The fire was lightning caused and has already burned 6,300 acres, northwest of Jackson Lake.

The Lizard Creek Campground, the Flagg Ranch and Headwaters Campground within Grand Teton National Park have all been evacuated.

There is no estimation as to when the closed areas will reopen.

Elsewhere, the Maple fire has burned 27,000 acres plus in YNP, and is nearing the main road connecting the Park's West entrance and Madison Junction.

Fire crews estimate that the fire will not cross the highway, which is still open, however pilot cars could be used to escort motor vehicle traffic safely through the area.
