Typically by mid-October firefighting agencies in Oregon have downsized their ranks of seasonal firefighters and are preparing to enter winter mode. But the Klondike Fire west of Grants Pass, after being dormant for weeks, exploded back to life on October 14 and in a big way. Within a matter of hours it burned an additional 4,968 acres to bring the total up to 172,287 acres.
According to an article in the Mail Tribune it was transporting burning embers into the atmosphere that started fires six miles out ahead of the flaming front:
“Extreme spotting” propelled fine embers up to six miles ahead of the main fire, dropping the live ash right between firefighters’ tents and close to people’s homes.
“We even had to move our own fire camp,” [information officer Kale] Casey said.

The Incident Management Team posted an update on Tuesday October 16:
Fire personnel focused all efforts to ensure that Sunday’s wind driven spot fires did not damage any of the homes in the Oak Flats, Spud Road and Agness area. Fire managers estimate that the weekend wind event resulted in approximately 5,000 acres of new growth to the west of the primary containment lines. Level 3 evacuations remain in effect for these areas while fire crews and engines work to construct and link together new and existing containment lines.
The Oregon State Fire Marshal’s five structural task forces that arrived yesterday have split into day and night shifts to ensure that all homes under evacuation are protected. These resources include twenty engines and five water tenders with firefighters from thirty-three different fire agencies from across the state.
Fire behavior moderated significantly yesterday as the 30 mph winds over the weekend diminished significantly, allowing fire firefighters to attack spot fires directly. Containing the remaining spot fires east and west of the Illinois River and west of the 3577 Road is the primary objective for all fire personnel.
