The Fishhawk Fire west of Cody, Wyo., grew 500 acres Wednesday and now covers 4,581 acres, fire officials said.
Firefighters got their new estimate from infrared mapping from an overflight. A Type 2 incident management team is being briefed on the fire Wednesday.
“This fire is in some rugged, hazardous terrain. Our number one priority is the safety of firefighters and the public; we are being tactical about what resources we use where and when it is safe to do so,” said Incident Commander Jay Slagowski in a statement.
The fire is within the Washakie Wilderness near Yellowstone National Park. The cause remains under investigation.
