Yellowstone National Park is reporting a fire that started Monday afternoon about three miles east of the South Entrance. The Snake Fire is now estimated to be about 40 acres in heavy timber, but little else is known about it. Park Spokesman Al Nash says a helicopter crew from Grand Teton National Park was dispatched to check out what is there. The fire is reported to be along the boundary between the Bridger-Teton National Forest and Yellowstone National Park. Consequently, Firefighting efforts will be jointly managed by the Bridger-Teton National Forest, Grand Teton National Park, and Yellowstone National Park.
