Duluth, MN (NNCNOW.com) --- The Duluth Fire Marshal's office is investigating what sparked a morning fire at a house along West 6th Street.
Fire crews were called before seven Tuesday morning on the report of a structure fire along the 4200 Block of West 6th Street.
Upon arrival, firefighters saw heavy smoke coming from the upstairs apartment.
Sub–zero temperatures quickly froze accumulating pools of water on the road, and made fighting the blaze difficult.
Residents told investigators that they were awakened by their smoke detector, and saw flames and smoke coming from the bathroom ceiling.
The occupants tried to put out the blaze with an extinguisher, but were unsuccessful.
The Northland Chapter of the American Red Cross is assisting the affected families.
"People are pretty devastated. It's not something you expect—to wake up in the morning have a fire that... turns your life upside down," said Red Cross Executive Director Dan Williams. "So, understandably, it's pretty overwhelming."
Damage to the structure and contents is estimated at more than $50,000. No one was hurt in this incident.
The cause of the fire is not known at this time.
21 firefighters from Lincoln Park, Spirit Valley, and downtown Duluth responded to the incident.
