Lake Louise avalanche victims not heard from in 7 days: RCMP

The father and son killed in an avalanche in Lake Louise, Alta., had not been heard from in seven days, say local RCMP.

They were reported missing on March 14 after failing to check out of the Chateau Lake Louise and RCMP then requested the help of Parks Canada Search and Rescue personnel to help look for the two Saturday afternoon. However, they had last been spoken to on March 9 when they rented their toboggan from the hotel.

RCMP say it's not clear when the avalanche was triggered.

A Parks Canada dog handler found the victims buried under debris at the base of Mount Fairview on the shore of Lake Louise.

Their names are being withheld pending notification of their next of kin.

It`s been a bad weekend for snow slides.

A 36-year-old man from Lloydminster, Sask., died of injuries he suffered Friday night in an avalanche near Blue River, B.C., about halfway between Kamloops and Jasper, Alta.

And a 38-year-old man from Calgary was critically injured Saturday when he and some fellow skiers triggered an avalanche in Alberta's Banff National Park.
