Wildfire blocking entrance to Yellowstone smolders on

Firefighters chopped down trees and searched for hot spots on steep hillsides Sunday as they battled a wildfire that has blocked an entrance to Yellowstone National Park.

Wildfire managers said their top priority is clearing a highway that leads to Yellowstone and protecting campgrounds, buildings and archaeological sites. They also are making sure there are no flare-ups or falling trees that could cause injuries or death.

Strong winds blew down several trees Saturday, blocking some roadways. Travelers have been warned to be cautious on roads around the park that remain open.

The fire that began last month in neighboring Grand Teton National Park is blocking Yellowstone’s south entrance, near the resort town of Jackson. Yellowstone also has entrance stations near Cody and in Montana.
