Firefighters continued to battle at least five wildfires west of Denver Friday afternoon. Colorado has seen average high temperatures in the low 90's this past week. The summer heat mixed with the dry climate creates a breading ground for wildfires in Colorado, fires which are often fueled by shifting, unpredictable winds and afternoon thunderstorms.

East Rim Fire

The East Rim fire in southwest Colorado has burned more than 689 acres since July 2, according to InciWeb, an incident information system used by eight federal agencies to monitor disasters.

The fire was started by an afternoon lightning storm in the western part of the San Juan National Forest. At least 75 firefighters are working to contain the fire which was at three percent containment Friday. The land is mostly owned by the U.S. Forest Service and the Bureau of Land Management.

Gutzler Fire

The Gutzler fire has consumed more than 1,000 acres as of Friday afternoon. No structures have been threatened or destroyed. A nearby campground has been temporarily closed to allow firefighters full access to the area. The fire began July 2 around 1 p.m., according to InciWeb. It was at three percent containment Friday as more than 175 firefighters battle the blaze in White River National Forest, 20 miles north of Vail.
