7 p.m.: Human activity caused a wildfire that sparked near Frisco and Interstate 70 on Wednesday afternoon, according to the U.S. Forest Service.

White River National Forest public affairs officer David Boyd said around 6:30 p.m. Wednesday that the Meadow Creek Fire burning near the Meadow Creek trailhead off I-70 Exit 203 in Frisco is about 1.3 acres in size.

Boyd said that firefighters have stopped the forward spread of the fire and expect to keep it that way until morning. But overnight, drivers on I-70 should exercise additional caution as smoke could settle creating low-visibility conditions, he said.

“They’re still working on it,” Boyd said. “It’s not contained but it’s not actively growing.”

The fire is burning in “fine fuels and shrubs” like grass, sage and aspen understory, Boyd said. That is what put up the smoke that alerted Summit County residents to the wildfire earlier this afternoon, he said.

While conditions are dry in Summit County and fire danger is at very high, Boyd noted that the shorter days with less direct sunlight and lower temperatures can aid firefighting efforts.  When the sun goes down, the temperature tends to decrease while the humidity increases so “typically we’re going to see the fire behavior diminish,” he said.

Crews will continue to work overnight and into tomorrow to make sure the wildfire is contained, Boyd said. He said that human activity caused the wildfire but that it remains under investigation, so he cannot share further details at this time.

“We’re not expecting much activity overnight but we’ll be monitoring it,” Boyd said.

6 p.m.: The cause of the wildfire burning north of Interstate 70 near the Meadow Creek trailhead outside of Frisco is still under investigation, and crews are still on scene.

The U.S. Forest Service is coordinating a response to the fire with the Summit County Sheriff’s Office, the Red, White & Blue and Summit Fire & EMS fire protection districts and the Colorado Division of Fire Prevention and Control, Boyd said. He estimated that there are about 30 firefighters and support personnel on scene.

“We’re on it,” Boyd said. “We have the resources and it is accessible, so we’re not anticipating major control issues. But we’re still in the response phase.”

Boyd noted that the fire danger in Summit County is elevated amid what has been a dry fall season. He said the wildfire demonstrates why people should take the current fire restrictions in place seriously.

“People need to be alert, use common sense and be sure they’re following the fire restrictions,” he said.
