NORTH OGDEN — Firefighters achieved 50% containment of a grass fire east of North Ogden by Wednesday morning, the Weber Fire District said.

The blaze covered 78 acres and state, federal and local fire crews planned to focus Wednesday on further containment and dousing of hot spots, the district said on its Facebook page.

Overnight, the fire had limited growth, but smoke was seen Wednesday morning from higher in Coldwater Canyon.

About 80 firefighters and two helicopters were working on the fire.

The district said investigators tentatively concluded the fire was human caused and accidental.

Power lines through the fire area were not part of the cause, the district said.

Firefighters had to work around power lines, some of which were downed by the fire.

The U.S. Forest Service urged people to stay away from the Coldwater Canyon trailhead and the nearby Bonneville Shoreline Trail while the fire is active.

The fire has not threatened any structures.

Forest Service spokesperson Kim Osborn said Wednesday afternoon that fire bosses planned to have a crew camp atop the mountain Wednesday night to monitor hot spots.

Firefighters have seen more than the usual numbers of human-caused fires this season, Osborn said.

“We’ve had a lot more people out recreating,” she said. “We remind people no fireworks are allowed on the national forests, ever.”

Properly extinguishing campfires and not idling vehicles over patches of grass also help prevent fires, she said, adding that target shooting can cause fires in hot weather as well.

“People just need to be heads up and aware that it doesn’t take much to start a fire in hot, dry weather,” Osborn said.
