This is what it looks like after you've fought a fire in a wind chill of minus 50

From CNN's Gianluca Mezzofiore

It's insanely cold in Wisconsin -- and it's about to get even colder -- but that's not stopping firefighters from doing their duty.

Cameron Fire Department Chief Mitch Hansen was pictured with a frozen beard and after battling a house fire in minus 50 wind chills Wednesday. "The fire gutted the home but everybody got out safe. We saved what items we could for them," Tony Paulson, one of the firefighters, told CNN.

"There was minus 50 wind chills. You're pretty much froze stiff on the outside but warm on the inside."

Assistant Chief Bimbo Gifford, who took the picture of Hansen, said he's been a volunteer with the department for decades and this is the first time he had to battle a fire with such freezing temperatures.

"It's tough. We're a small team of volunteers but we're careful and trained," he told CNN. "When it's that cold you just can't move."

The guard is changed every hour when the cemetery is open, Major Stephen Von Jett said. At night, the shifts vary.

"Our Soldiers have great cold weather equipment that allows them to brave these conditions, but it's their commitment to the mission, and to representing the US Army's commitment to the American people that keeps their backs straight against the wind," Von Jett said.

Watch steam rise off of a freezing Lake Michigan

The Windy City has become the frozen city.

CNN's Leonel Mendez took a time lapse video at sunrise showing steam rising off icy Lake Michigan.

Why the lake is steaming: Steam can rise off a lake when the water is warmer than the cold air above it. Here's how NASA describes it: "As cold, dry air moved over the lakes, it mixed with warmer, moister air rising off the lake surfaces, transforming the water vapor into fog — a phenomenon known as steam fog."
