Over 17-hundred firefighters are working to contain the Calaveras Complex fire.
Nearly 44-hundred acres in all have been burned, and full containment is expected Tuesday evening.
The three fires began Friday afternoon.
The Armstrong Fire, which began around 2pm Friday, is estimated to have burned up to 82 acres.
The Mineral and Copper fires however were much larger.
The Mineral Fire has burned 876 acres and the Copper fire has burned about 3445 acres.
Both the Armstrong and Copper Fires are 90 percent contained as of today… with the Mineral Fire, out near Sheep Ranch, is estimated to be 65 percent contained.
One wooden summer cabin and one mobile home have been confirmed lost, and so far one minor injury to a firefighter has been reported.
While the cause of the Copper Fire has been determined to be a vehicle with mechanical problems travelling eastbound along Highway 4, officials aren´t so sure about the Armstrong and Mineral Fires.
In all, 150 residences and 40 outbuildings are threatened by the Calaveras Complex Fire.
And officials from the California Department of Forestry and Fire Protection say… while allowing the 210 evacuated residents to return home is a high priority, it will only be done when it´s deemed safe to do so.
Officials are reviewing the situation every six hours.
