Explosive peat moss

Peat Moss Flame

In at least one location in Alberta, Canada the peat moss is so dry it can turn to dust when disturbed, and in the presence of sufficient heat and oxygen is damn near explosive.

It’s a good example of the Fire Triangle: Heat + Fuel + Oxygen = Fire

One of Air Spray’s four-engine L-188 Electras had a problem with its landing gear June 22 and had to make an emergency wheels-up landing at Red Deer Regional Airport in Alberta.

Red Deer News Now reported that according to Graham Ingham, CEO at the airport, the incident happened around 12:20 p.m.

“We had an Air Spray air tanker, an Electra-type aircraft, perform an emergency landing due to the fact it couldn’t get its main landing gear down. After a couple of attempts, they decided that it would be safer to do a wheels up landing, and subsequently they did. Thankfully they came to a complete stop. There were no injuries, no fire and it was the best outcome for everyone.”

Mr. Ingham said two pilots and two other people on board walked away from Air Tanker 490 without any injuries.

The video below shows what looks like an excellent landing, considering the circumstances.

Firefighters, heavy equipment, and aircraft continue to work on the McMillan Complex in Alberta which is approximately 22km northeast of the junction of Highway 88 and Highway 754. The complex is comprised of 4 wildfires that are a combined 215,065 hectares (531,439 acres) in size. Alberta Fire photo.

At least five hotshot crews from Oregon and Montana will be leaving Wednesday to assist with the wildfires in Alberta.

Kathy Bushnell of the Helena-Lewis and Clark National Forest said Montana hotshot crews from the Helena, Lolo, Bitterroot and Flathead national forests will travel north with the Rogue River Hotshots from Oregon.

Deb Schweizer of the USFS office in Boise told Wildfire Today that an additional 15 personnel are being mobilized for a variety of overhead positions.

Chuckegg Creek Fire in Alberta grows to over half a million acres

Will it become a million-acre “gigafire”?

Map Chuckegg Creek Fire Northern Alberta
Map of the Chuckegg Creek Fire in Northern Alberta at 3:50 a.m. MDT May 30, 2019. The shaded areas represent heat detected by a satellite during the previous seven days.

The Chuckegg Creek Fire in Northern Alberta near the town of High Level was very active over the last 48 hours while being pushed by strong winds. Exhibiting extreme fire behavior, it grew to the south about 11 miles, and while moving 12 miles to the east it crossed Highway 35 and jumped the Peace River both north and south of the ferry crossing on Highway 697.

Alberta Wildfire estimated it has burned 230,000 hectares, or 568,000 acres.

Below is an excerpt from an update by Alberta Wildfire about the Chuckegg Creek Fire, issued May 30, 2019:

The Chuckegg Creek Fire experienced extreme fire behaviour yesterday with significant growth to the south towards Paddle Prairie, across Highway 35 by Highway 697 and spotted across the Peace River. Continued hot and dry conditions along with variable, gusty winds have proved a challenge to firefighting efforts and safety. Municipal firefighters and heavy equipment responded, with structure protection established as possible to the south of the fire. The fire also experienced growth to the west and continued fire activity on the north part of the fire around Watt Mountain.

Firefighters, heavy equipment, and aircraft are assessing the situation given the recent fire growth and will focus on priority areas. Structural protection and municipal firefighters are working to protect values. The weather forecast today anticipates cooler temperatures and higher minimum relative humidity, though winds today are expected to remain gusty and are expected to come primarily from the north.

I believe that the fire started during the week of May 12. It reached the 100,000-acre threshold to become a “megafire” on May 20. Now that it has easily grown to 568,000 acres, I wonder if it will reach a million acres to become a “gigafire”. A bushfire that started October 11, 2018 in Western Australia 120km southeast of Broome burned 880,000 hectares, or 2,174,527 acres.

The weather for the next seven days at the fire’s location will be variable, with a chance of rain on Saturday, Monday, and Thursday of next week, so there will not be many days conducive to explosive fire growth.
