EMMETT - Multiple agencies are working to stop a grass fire burning near Emmett. A spokesperson for Boise BLM confirmed the fire has already destroyed one home and an outbuilding.

No other homes are currently threatened.

The fire started around 1 p.m. Wednesday afternoon on Old Freezeout Hill along Idaho 16. An official said the highway remains open, but there are closures on secondary roads in the area.

At last check, the fire was measured at 20 acres.

The owner of the home that burned tells KTVB it was a double-wide trailer that was used for storage. Chris Snyder said the trailer was a total loss, along with an RV camper, flat bed trailer, and a large shed. There is another home on the property where Snyder and his family lives that wasn't damaged.

Snyder says firefighters told him the fire was caused by fireworks that were set off at the bottom of the hill. BLM officials say the fire was human-caused, but the specific cause is still under investigation.

Gem County Fire, Eagle Fire, Middleton Fire and the BLM are assisting in firefighting efforts.

High temperatures, low humidity and gusty winds have made containment more difficult, officials said. The fire is still considered active, but its forward progress has been stopped.

Managers hope to have the fire fully contained by 8 p.m. Wednesday, and controlled by 10 p.m.
