Cooler weather continues to help keep fires in Yellowstone under control, allowing park officials to reopen the Mud Volcano area north of Fishing Bridge.
The Mud Volcano and other areas along the Yellowstone River have been closed for over a week because of the Alum Fire. Some trails, picnic areas and road pullouts remain closed Monday.
The Alum Fire has burned about 12 square miles. The fire is only a few hundred yards from the Grand Loop Road but isn't growing much.
Park officials are allowing the fire to burn without interference to help the ecosystem. Meanwhile, they're clearing vegetation northwest of Bridge Bay to protect buildings in case the fire moves that way.
Four smaller fires continue to burn slowly in mostly remote areas of Yellowstone.
