What does this mean for you if you're visiting Yellowstone National Park? Possibly nothing--we expect most roads to remain open, the skies to remain relatively free of smoke, and the landscapes and geysers to be just as breathtaking as they always are.
It IS possible that a section of the Grand Loop Road will close occasionally between Hayden Valley and the Lake area if the Alum fire reaches the road and debris impacts or threatens to impact the road. Rangers & fire managers will be paying close attention to fire movement, so prepare for temporary delays as the fire nears the road. Every effort will be made to keep the road open.
Be heads-up and fire aware, and pay attention to road signage and direction from rangers. Have a great trip!
