Bureau of Land Management fire investigators have determined that fireworks caused Sunday’s fire that was 11 miles west of Rexburg on BLM land.

The Menan Butte area fire stretched 4,537 acres and is 70 percent contained. Full containment of the fire is expected by 10 p.m. Tuesday.

“This fire is disappointing not only because all fireworks are prohibited on BLM lands, but because that area is highly susceptible to wildfire.” said Jeremy Casterson, Upper Snake Field Manager. “Firefighters were able to suppress this quickly, but may not be so fortunate in the future. These fires affect ranchers, hunters and other public land users. ”

The wildfire, ignited Sunday afternoon, was one of the largest to hit East Idaho this season.

The fire caused the closure of Highway 33’s eastbound lanes near Interstate 15 for several hours on Sunday evening.

The 2019 Fire Prevention Order prohibits specific fire-related activities on public land from May 10 to October 20. The Fire Prevention Order makes it illegal to possess or use fireworks on BLM-managed lands in Idaho.

Any person who knowingly and willfully performs any act restricted by the Fire Prevention Order could be subject to a fine and held responsible for fire suppression and/or rehabilitation cost.
