*** Four Teens Die in Canadian Rockies Avalanche *** 27th November 1997 CANMORE, Alta. (CP) -- Four teens were killed Saturday in an avalanche in Alberta's Rocky Moutains after they hiked into the back country in search of snow. The teens -- three males and one female -- were all 17 and from Calgary. Searchers retrieved the bodies from near the Fortress ski hill west of Calgary on Sunday after a parent reported the youths missing when they did not return home Saturday. Their bodies were found close together under a metre of snow and investigators believe they were walking through a gully when the avalanche hit. "Nobody was skiing at that point and they were all together .. because they were together they were probably joking and laughing," and probably didn't hear the sound of the avalanche, said Kananaskis Country ranger George Field. Unseasonably mild temperatures and lack of snowfall have kept most Alberta ski hills closed this season. A search was launched Saturday, but called off at nightfall. At first light Sunday, park rangers discovered tracks leading into a fresh slab avalanche in the out of bounds bowl to the right of the double chair on the backside of Fortress Mountain' main ridge. A national park warden scouring the site with a rescue dog found the bodies after a brief search. Parents of the dead teens gathered at the Fortress ski hill lodge while the bodies were taken to a waiting ambulance at the bottom of the hill. Tracks indicate the teens had hiked up the front of the closed ski hill and over a ridge in search of some snow where they could ski and snowboard. Searchers believe the four were still hiking because they found a backpack with a snowboard still inside. "Everybody feels that going into these gullies that have snow in them .. is the place to go because that's where it's deep," said Field. But warm Chinook winds that have blown across Alberta for the past week have built up unstable layers of crust on top of the snow. "There has been some crust layers set up because of Chinook-type temperatures and then they're frozen again. These are the layers that caused the problem here," said Field. The warmer temperatures also contributed to several recent accidents involving ice climbers in the Alberta Rockies. Ice conditions were suspected in the fall of a British man who was climbing Mount Kidd Falls near Nakiska in Kananaskis Country on Nov 23. The man was flown by rescue helicopter to a Calgary hospital with undetermined injuries. The climber apparently lost his grip or the ice gave way. Later the same day, wardens in Banff National Park responded to a call at Professor Falls on Mount Rundle, about five kilometres from the town, where a man had fallen about five metres and injured his knee. Two ice screws appeared to have dislodged. -------------------------
