One of the largest wildfires to hit eastern Idaho so far this season has scorched thousands of acres west of Rexburg.
As of 10 p.m. Sunday nearly 80 firefighters with help from several air tankers were battling the 7,500-acre blaze, which ignited near the Menan Butte area late Sunday afternoon.
The flames are not currently threatening any structures and thus far there have been no evacuations or injuries, authorities said.
On Sunday night the East Idaho Interagency Fire Center in Idaho Falls reported that winds of up to 20 mph were fueling the fire's spread in grass and brush on flat terrain.
The wildfire is burning on Bureau of Land Management land about 11 miles west of Rexburg.
Firefighters are trying to douse the flames with water from the several fire engines on the scene while using bulldozers to build fire lines to contain the blaze, the fire center said.
Firefighters hope to have the wildfire contained by late Tuesday night, but as of Sunday night the fire was zero percent contained.
The fire caused the closure of state Highway 33's eastbound lanes near Interstate 15 for several hours Sunday evening.
The fire center said the cause of the wildfire is currently unknown but under investigation.
