The Lone Star Fire in Yellowstone National Park has grown to 960 acres as of Sunday morning, according to a National Park Service press release.
The release said an approaching cold front brought warmer temperatures and gusty winds Saturday that increased fire activity.
There are 49 personnel assigned to the fire; two more engines arrived Saturday to help protection around key Old Faithful infrastructure.
"Work will continue on Sunday near an aboveground power line, substation, and park cabins," the release stated. "A park resource team finished an archeological survey in the Old Faithful developed area and will now focus on mapping sensitive riparian habitat and rare plants. This information will help the incident management team minimize impacts to these important natural resources."
The Grand Loop Road and day-use areas between Old Faithful and West Thumb Junction are now open but could close at any time with increased fire activity.
The Lone Star Fire was first reported on Saturday, August 22, at 5:15 p.m. about 3 miles south of Old Faithful. Lightning has been identified as the cause of the fire.
All Yellowstone entrances are open, although fire danger remains very high. Campfires are not currently allowed in the backcountry.
