BLM fire officials say the fire was human-caused but it remains under investigation. Crews are working hotspots along the perimeter, and they expect to have it under control by 2 p.m. Thursday.
At one point, Idaho 21 was shut down between Hilltop and High Bridge but by 2 p.m., one lane of the highway was re-opened, a dispatcher said.
Last July, a grass fire that started about 300 yards south of Hilltop Station burned more than 4,300 acres. That fire was called the Mile Marker 14 fire.
