SHOSHONE -- A lumberyard and an outbuilding were destroyed as fire crews battled a wildfire near Shoshone.

The Lagoon Fire, measured at 1,412 acres Thursday afternoon, was sparked by a lightning strike around midnight Tuesday. According to the Bureau of Land Management, crews will assess other structures in the area of the fire Thursday to see whether there is additional damage.

The wildfire spurred evacuations in Shoshone Wednesday as the fire burned nearer to homes. People living on both sides of Highway 93, north to the Grape Creek Subdivision, were urged to get out. Evacuations were lifted that same night after firefighters got the upper hand on the flames.

Highway 75 was shut down for some time Wednesday as well, but has since reopened.

But BLM spokeswoman Kelsey Brizendine said residents should remain alert. Evacuations could be reinstated if the fire surges back toward town, she said.

"The terrain is so difficult that if we get any kind of wind event, the potential for it to kick back up is there," she said.

No primary homes have burned, Brizendine said. The lumberyard that burned was the locally-owned Sticks and Stones, which mainly manufactured fence posts and poles.

Officials said Thursday evening that the fire is now 70 percent contained, and that they expect full containment by Friday night.

The Notch Butte Rangeland Fire Protection Association, ten engines, an attack crew, a hotshot crew, four handcrews, four dozers, six overhead, one air attack, one camp crew and several other several air resources have been assigned to the fire.

The Lagoon Fire is currently burning actively in grass and brush.Crews are working now to put in "as many containment lines as possible" and shore up structure protection, Brizendine said.
