British Columbia: Chelaslie River Fire

map Chelaslie River Fire

The Chelaslie River Fire 126 miles west of Prince George has burned over a quarter of a million acres in British Columbia. Authorities have issued evacuation orders for Entiako Provincial Park and the west half of the Tetachuck Lake area.

The 264,000-acre (107,000 hectares) fire, discovered July 8, started from lightning. It is being fought by 290 personnel and 18 helicopters.

The description of current activities found on the British Columbia government website uses some jargon that may be foreign to firefighters in other countries:

Heavy equipment continues to be utilized to establish new machine guards and contain new fire perimeters. Firefighters are establishing new contingency guards and mopping-up spot fires outside the fire perimeter. A second Wildfire Management Branch camp has been implemented on the Northern side of this fire.

British Columbia town emptied as fire advances

 


The entire town of Hudson’s Hope in northeastern British Columbia has been emptied as the nearby Mount McAllister fire spreads out of control.

The wildfire was ignited by lightning on Sunday, and had grown to more than 20,000 hectares (more than 49,000 acres) by Thursday.

Local officials went door-to-door through the town, urging the town’s 1,150 residents to evacuate, The Huffington Post reported. 

The Mount McAllister fire is one of more than 100 wildfires currently raging in British Columbia, where tinder-dry conditions have fueled one of the worst fire seasons the province has seen in a decade.

Canadian fires continue to rage, “worst fire season in years”

Dry heat is fueling several out of control wildfires in Alberta and British Columbia this week, where fire officials say this is the worst fire season the region has seen since 2003.

There are 156 fires burning in Canada’s Northwest Territories, The Toronto Sun reports.

As of Monday morning, around 11 fires were burning out of control in Alberta, according to the province’s wildfire situation report. Meanwhile, the explosive Spreading Creek fire near Banff National Park, British Columbia, is being held for the first time since lightning ignited it on July 3, The Calgary Herald reported. The fire had burned more than 6,800 hectares (around 16,800 acres) as of July 14.

The fire has intermittently shut down parts of the Icefields Parkway that winds from Banff to Jasper. Photos capturing its spectacular plume of smoke have sparked an international interest in the fire.

 

While fires spread on both sides of the national park, conditions are no different in BC’s interior, where a fire ignited on Tuesday in tinder-dry country near West Kelowna. The so-called Mount Boucherie fire had burned around 12 acres by Tuesday evening, and was being held by fire retardant lines, local media reported. The fire continued to burn into Tuesday night.

West Kelowna is in a fire-prone corridor known for regular wildfires. In 2003 in nearby Kelowna, lightning ignited the Okanagan Mountain Park fire, which went on to burn hundreds of homes and prompted the largest fire-evacuation in Canadian history.

I’ve spent some time in Kelowna and last year wrote a story about the Okanagan Mountain fire, ten years after the historic blaze. It had some eerie parallels to another wildfire, the Waldo Canyon fire, which I covered while working at The Gazette in Colorado Springs. Read my story on the Okanagan Mountain fire here. 

Affecting the spread of a fire by lighting more fire

This video showcases how firefighters in Kootenay National Park in British Columbia helped to prevent a fire from crossing a natural barrier by lighting more fire. The additional heat created convection and indrafts that allowed firefighters to affect the spread of the fire, resulting in them being able to protect structures and a highway. 

The video was created by Fire Information personnel working for Parks Canada, using a series of still images shot by Jon Large, who told us he “had a great viewpoint on the adjacent mountain!”

Thanks Jon, and Parks Canada.

Below is a description of the video from YouTube.

Using fire to fight fire may seem counter-intuitive, but a deliberately lit fire can be a very important tool in a firefighter’s toolkit. During the Numa Creek Wildfire in 2013, specialists burned away fuel in the wildfire’s path to slow its progress. They used a natural fire break and convective air currents to control the deliberately set fire and protect both the highway and structures below. Fire specialists rely on a thorough understanding of fire behaviour to successfully manage fires of all kinds. Where we see flames and smoke, fire specialists see prevailing winds, convective heat, in-drafts and more. This is what fire specialists saw during one operation on the Numa Creek Wildfire of 2013.

Looking back at the 2003 Kelowna wildfire

Even though I stayed overnight in Kelowna, British Columbia on a motorcycle trip last August, I was not aware of the nearby devastating Okanagan Mountain Park (map) wildfire in 2003 that destroyed hundreds of homes and threatened the lives of firefighters. Here is an excerpt from an article in the Kelowna Capital News:

During the 2003 Kelowna wildfire, a group of firefighters trapped in Kettle Valley were surrounded by 400 foot high flames, took shelter under fire trucks, and called home from their cell phones to say goodbye to their families.

“They couldn’t get out,” recalled former Kelowna fire chief and current city councillor Gerry Zimmermann as he welcomed more than 200 colleagues from around North America to the three-day Western Wildfire Conference in Kelowna Thursday morning.

But, everyone survived the Okanagan Mountain Park wildfire, even though 30,000 people were evacuated, 239 homes were lost in two nights and 60,000 acres were burned across the south slopes, 10 years ago this summer…
