Four people were caught in the avalanche and buried, the company said.

They were found through a transceiver search and deployed airbags.

The four people were extricated within 15 minutes of the avalanche, the company said, but the three guests did not survive.

The fourth person, a guide, was critically injured and flown by BC Ambulance to the Terrace hospital.

White Wilderness Heliskiing said the guide is now in stable condition and undergoing surgery in Vancouver.

“The WWH team sends its heartfelt condolences to the families and friends of the three guests who lost their lives in this incident. Our deepest sympathies are with the families of the victims,” the company said.

The remaining three people were confirmed to have died and they were recovered from the mountain, police said.

The second fatal slide occurred just a few hours later in a remote corner of northwestern B.C., near the Canada-U.S. border close to Skagway, AK.

Atlin RCMP received a Garmin SOS alert from a remote area near Klehini River and Pleasant Camp, approximately 350 kilometres west from Atlin.

RCMP said they were told an avalanche had occurred and one person was unconscious and CPR was being performed.

Atlin RCMP coordinated with Atlin Search and Rescue to plan an extraction, police said, and due to the remote location, a helicopter was utilized to access the area.

Upon arrival, responders confirmed that one person was dead.

Five people were extracted, police said, with the remaining four not hurt.

The BC Coroners Service is investigating the four deaths, RCMP said.

On Monday, Avalanche Canada classified the danger rating around Terrace as considerable and the area close to the B.C. / U.S. border as moderate.

Two snowmobilers were involved, police said.

“Other snowmobilers in the area provided assistance to the two snowmobilers involved while emergency personnel from the Creston RCMP, Search and Rescue, and BC Emergency Health Services responded,” they said in a news release Monday.

“Both men were extracted by the other snowmobilers, but sadly a 23-year-old man died at scene.”

No other information was released.

The death comes just a day after another avalanche killed a 15-year-old skier in Alberta.

The avalanche occurred in the Naskiska area, about 100 kilometres west of Calgary.

Avalanche Canada issued a warning that strong winds and new snow had fallen in the area overnight Thursday and into Friday, meaning the avalanche danger in the area was high.

There are now six avalanche-related fatalities in Western Canada so far this winter.
