The largest of the three, the Deep Creek Fire, is located nine miles west of Hayden, Colorado. It is almost 4,000 acres in size and only 12 percent contained.

The Deep Creek Fire is only five days old. It is spreading to the north, but fire command reports solid progress on the southern portion thanks to bulldozers and hand crews.
