Exact source of ignition still under investigation
By Summit Voice
SUMMIT COUNTY — Fire officials say they believe the Fourmile Canyon wildfire was human-caused, but they are still trying to determine the exact source of ignition.
Overall fire information is updated frequently at www.inciweb.org.
The wildfire west of Boulder has spread across about 6,300 acres and destroyed more than 130 structures, making it one of the most destructive Colorado fires in recent memory. As of Sept. 8, firefighting costs had already topped $2 million.
Fire officials issued a red flag warning for the area Thursday afternoon, anticipating that gusty winds and dry conditions could again lead to extreme fire behavior. More than 500 firefighters are at the scene and have the fire about 30 percent contained, with 75 engines, five helicopters and seven air tankers providing support. Full containment isn’t expected for another 10 days, according to U.S. Forest Service, who said the fire has high potential for growth and is burning in “extreme” terrain, with a heavy load of down and dead fuel, including beetle-killed Douglas-fir.
Emergency officials rescinded an earlier decision to re-open some areas temporarily, saying that a changing weather forecast calling increasing winds increased the risk of unpredictable fire behavior.
