An attempt to reach the peak of Mount Saskatchewan, a mountain in the Yukon, has ended short of the goal, according to a friend of the team of climbers who set out 12 days ago.

Dave Weightman, a co-worker of climber Steve Whittington,  told CBC News Wednesday that he was able to place a brief phone call to the climbers.

It was not immediately clear what forced the climb to stop, although Weightman said the team was waiting out a storm and that a helicopter was set to pick them up, possibly on Thursday.

All four climbers are reportedly safe.

Mount Saskatchewan's peak is at 3,500 metres.

The four climbers, all members of the Alpine Club of Saskatchewan, were hoping to become the first to reach the top.

The mountain is part of a range in Yukon’s Kluane National Park, where each peak is named after one of Canada’s provinces.
