Canadian artillery returns to the mountains of B.C. amid deadly 2023 avalanche season
In the high mountain passes of southeastern British Columbia, the Canadian military is mounting another winter offensive in its six-decade war against ice and snow. This year's campaign comes at the close of an unusually deadly 2023 avalanche season in the western Canadian backcountry.
The latest troop of artillery gunners arrived in Glacier National Park in mid-November with three 105-mm Howitzer field guns trained on the narrow valley walls overlooking the Trans-Canada Highway and the Canadian Pacific Railway.
The soldiers will remain on the deployment into the new year when another rotation of troops will continue the work until the fight is abandoned in late March or early April.
Canada's longest-running military operation began in 1961, the year before the Trans-Canada Highway fully opened.
Every year since, dozens of soldiers and Parks Canada avalanche forecasters have trekked out to the area northeast of Revelstoke, B.C., to participate in Operation Palaci, the world's largest mobile avalanche-control program.
During a rotation change, there can be up to 50 Canadian Armed Forces members at the operation's main mountain compound, an apartment-style complex that provides food and lodging for the mission.
From there, the soldiers set out to staff the guns from 18 designated firing positions, primarily located in Rogers Pass, where the road and rail snake through the Selkirk Mountains in the most avalanche-prone travel corridor in North America.
At more than 1,300 metres above sea level, Rogers Pass averages about 14 metres of snowfall per year and contains more than 130 active avalanche paths crisscrossing the busy highway. In the winter months, the federal government estimates up to 4,000 vehicles and 40 trains travel through the pass daily.
It was here on March 4, 1910, that Canada's deadliest avalanche claimed the lives of 58 railway workers tasked with clearing the tracks after an earlier slide. It was here too, in 2003, that seven Grade 10 students from a private school south of Calgary died after they were buried under a massive avalanche. Seven other students and three teachers were swept up by the avalanche but survived.

AVALANCHE CLOSURES COST $500K PER HOUR
Today, Parks Canada officials close a section of the highway while the gunners blast away at the unsteady snowpack before the shovels and ploughs come out to clear away the debris. With 270 pre-designated targets already dialed in, the Howitzers can fire effectively at night and in all weather conditions, hitting targets up to five kilometres away, Parks Canada says.
"Each shell is fired at a known trigger zone high up the slide path, creating a shockwave that releases an avalanche when snow conditions are right," the agency says.
In a slow season, they gunners will fire between 300 and 500 high-explosive shells into the mountainsides along the 40-kilometre corridor. During a busy year, the fire count rises to more than 1,000 rounds, according to Pedram Mohyeddin, a spokesperson for the Canadian Armed Forces.
Most highway closures for avalanche control last less than two hours, totalling around 100 hours of controlled closures annually, Parks Canada says.
"Highway closures in this area have an estimated $500,000-per-hour impact on Canada’s economy," Mohyeddin said. "The program continues to evolve to reduce highway closure times and improve safety for the travelling public, staff, and partners throughout the season."
Approximately 2,000 avalanches are recorded along the Trans-Canada corridor through Rogers Pass each year, with about 120 of those slides affecting the highway, Parks Canada estimates.
Sixteen people have been killed by avalanches in Canada in 2023, surpassing the national average of 11 avalanche deaths per year, according to Mary Clayton, a spokesperson with the Revelstoke-based Avalanche Canada.
Fourteen of those deaths were recorded in B.C., including five deaths in three separate slides near Glacier National Park.
