The Lone Peak Fire in Yellowstone National Park (YNP) stands at an estimated 763 acres as of Tuesday afternoon.
The fire, burning 3 miles southeast of Old Faithful, was first reported around 5:15 p.m. on Saturday. It continues to spread to the northeast, away from Old Faithful.
There are 37 personnel assigned to the fire. On Tuesday, crews were focused on creating fire protection plans for developed areas, according to a press release from YNP.
"Fire suppression efforts will be based on the fire’s movement towards park infrastructure such as historic buildings, a water treatment plant, communication towers, and other resources at risk," the release said.
The Grand Loop Road south of Old Faithful between Old Faithful and West Thumb Junction remains closed, as are trails leading to Shoshone Lake and Lone Star Geyser.
All entrances to Yellowstone are open, as are the Old Faithful developed area and West Thumb Geyser Basin.
Campfires in the backcountry are not allowed as fire danger in the Yellowstone area remains very high.
