A prescribed fire on the Wallowa-Whitman National Forest escaped the day after it was conducted in northeast Oregon. The 2,000-acre project was ignited with a helicopter on Thursday, September 29 as a continuation of previous prescribed burning activities in the Minam drainage within the Eagle Cap Wilderness Area about 21 miles northeast of La Grande, Oregon.
Late in the afternoon of the next day, Friday, during a helicopter flight to check the status of the project, fire managers found a spot fire east of the burn area across Trout Creek. Due to the time of day, it was determined that firefighters could not safely access the spot fire until the following day.
Early Saturday, October 1, a powerful thunderstorm moved through the area bringing stronger than expected winds and very little moisture. As planned, firefighters hiked into the spot fire on Saturday and found that the winds had spread the spot fire to the east, upslope onto Cougar Ridge, and ultimately outside the planned prescribed fire area.
The Minam Fire was declared an escape Saturday afternoon, October 1st, when fire managers determined that they would not be able to contain the portion of the fire that had spread outside of the planned perimeter within the next 24 hours, which is a criteria for declaring an escaped prescribed fire.
Cooler weather kept the spread of the fire minimal into Sunday as additional crews and aircraft arrived on scene to support the suppression efforts.
As of Sunday, October 2, the escaped fire had burned 750 acres.
