A father and son have been killed in an avalanche in Lake Louise, Alta.

A Parks Canada release says RCMP requested the aid of Parks Canada Search and Rescue personnel to help search for the two Saturday afternoon.

The release says 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.
