According to Carabineros police captain Alvaro Herrera, the skiers' bodies were spotted from a fly-over of a multi-agency rescue team's helicopter, but were not yet recovered as of Tuesday afternoon due to the treacherous terrain.

Recent posts from Fransson's Facebook page revealed that he and Auclair were on a skiing expedition that was being filmed for a video project set to be released by fall. The project was in collaboration with filmmaker Bjarne Salen and photographer Daniel Ronnback.

The other two members of the team, both from Sweden, were able to survive the avalanche unharmed.

According to ESPN, Salen had raised an alarm for rescuers about an accident during the massive avalanche on Monday afternoon.

The group had been in the area for almost a week and had been filming for the video series since they arrived.

The two renowned skiers were popular for extreme skiing exploits in some of the most remote and dangerous mountains around the world.

Fransson caught the world's attention after he descended the Denali's south face in 2011 and had earned great respect from the skiing industry after he survived the 2010 avalanche in Aiguille de Verte along the French Alps that nearly killed him.

Meanwhile, Auclair helped pioneer modern skiing and became a member of the New Canadian Air Force after he ditched mogul skiing.

He co-founded the Armada Skis and was famous for his versatility both in urban settings and high peaks around the world.

He is also known for his All.I.Can video segment filmed in and around Trail in 2011, which was dubbed as one of the most unique clips in skiing history.
