Firefighters battling a house fire in Hammond, Indiana, in Wednesday's -22 degree weather ran in to a major problem: the hose water kept turning into ice.
"Everything got slowed down and even a fire hydrant was frozen," Hammond Fire Chief Jeff Smith told CNN. "I'm currently thawing out and so is my crew.”
The frozen water and cold temperatures created a number of issues for the firefighters.
"A couple guys slipped and fell on the ice, including me. They looked like snowmen, ice was falling and cracking of them," Smith said. "It was a difficult situation. Cold weather takes a little bit extra time."
The fire was reported 7:15 a.m. ET, but it took firefighters several hours to finally extinguish the flames. An older woman who lived in the home remained missing as of Wednesday afternoon, Smith said. The cause of the fire is under investigation, but firefighters think it started in the basement.
That part of the house, he said, was "filled with a couple feet of water that's turned into ice."
All the runners in the Arrowhead 135 ultramarathon have completed the race, according to the race’s Facebook page.

At least nine deaths have been linked to the extreme weather and cold temperatures.
There have been at least three weather-related deaths following crashes in Iowa since Sunday, Iowa State Patrol Sgt. Nathan Ludwig told CNN. An additional death was reported at the University of Iowa on Wednesday morning.
Here's what we know so far:
- A 9-year-old boy from Nebraska was killed Sunday in a crash in Iowa when his family's vehicle slid off Interstate 80 and into a ditch in Cass County. At the time of the accident, there was freezing rain and icy conditions on the roadways.
- A 31-year-old man was killed Monday on Interstate 80 in Iowa when the car he was riding in crashed into a telephone pole in Polk County. According to the Iowa State Patrol report, the vehicle was traveling at a high rate of speed.
- A 50-year-old woman was killed Monday when a semi-trailer rear-ended a car she was riding in on Interstate 80 in Iowa. According to Iowa State Patrol, the roads were icy at the time.
- A University of Iowa student died Wednesday after he was found unresponsive on campus. The student was taken to a hospital, where he later died. His death is believed to be weather-related, according to the University of Iowa.
The US Coast Guard rescued seven people Tuesday after they became stranded in an ice shanty near Sturgeon Bay in 4 below zero weather.
The group had become stranded on the ice due to the bitter cold and problems with their utility vehicle, so they propped up an ice shanty, according to the Coast Guard. The weather at the time was 4 below zero with -30-degree wind chills.
Coast Guard and Wisconsin Department of Natural Resources crews loaded the group on boats and took them to shore. They suffered no apparent injuries, the Coast Guard said in a statement.
You've seen the videos by now -- people toss boiling water into the freezing air and are rewarded with a puff of snow.
But did you know that with a touch of food coloring, one could make it snow red, white and blue (but mostly white)?
That's what one group of friends discovered this afternoon while gathered at Chicago's Lottie's Pub when they decided to test that theory.
