Canadian climber rescued from New Zealand ravine

A Canadian climbing alone in New Zealand had to be rescued by helicopter after she ended up "in an extremely precarious position" on the side of a ravine, New Zealand officials said Monday.

The woman, whose age and hometown were not immediately released, ended up in a spot where she was unable to ascend or descend at the edge of the Goldney Glacier, on the eastern side of Mount Rolleston, a mountain on New Zealand's South Island with an elevation of about 2,275 metres.

The Rescue Coordination Centre New Zealand (RCCNZ) started the rescue after they detected a personal locator beacon just after noon local time Monday. A Eurocopter AS350 from the town of Greymouth arrived on the scene at around 1:20 p.m.

Michael Flyger, spokesman at government-owned Maritime New Zealand, told CBC News that the woman ran into trouble at about 1,500 metres above sea level. He wasn't sure how long she had been on the slope, but that it was likely a number of hours and that she was not injured.

Rescue mission coordinator Greg Johnston said after assessing the situation the helicopter pilot flew to nearby Arthur's Pass to pick up a member of the cliff rescue team before returning to winch the woman to safety.

"She was unharmed but was in an extremely precarious position, and unable to move," Johnston said. "It was a quite a challenging rescue but well executed by the helicopter crew."
