Goltra Fire grew "significantly" overnight, Jeffco sheriff says Wednesday

JEFFERSON COUNTY, Colo. — The Goltra Fire grew "significantly" overnight, the Jefferson County Sheriff's Office said Wednesday morning , jumping to 200 acres.

Additional resources were ordered for a greater impact on the fire, the Jeffco sheriff said Wednesday morning, and US 6 remained shut down in both directions.

The fire burning near Clear Creek Canyon in Jefferson County was first reported around 4 p.m. Tuesday near Tunnel 1 in the canyon. In an update at 7:46 p.m., the Jefferson County Sheriff's Office said the fire was “guess-timated” to be 10 acres.

Smoke from the Goltra Fire was visible from the Denver area Tuesday afternoon and evening, including from Alumni Field at Marv Kay Stadium at the Colorado School of Mines in Golden.

In a subsequent update at 10:30 p.m. , the sheriff's office said evening down-canyon winds caused "some erratic fire behavior." Highway 6 and travel along the canyon were both closed until further notice, the sheriff's office said.

Lightning is suspected of starting the fire, the Jeffco sheriff's office said Tuesday night.

Interstate 70 and Highway 93 are both open, according to Denver7 Traffic Jayson Luber, and are good alternative routes.

No evacuations were ordered, and no structures were threatened as of Tuesday night.

There will be a news conference with updates on the Goltra Fire at 8:45 a.m. Wednesday, according to the public information officer for the Jeffco sheriff.
