The helicopter has managed to land a party of six rescuers at the base of the Rudolph Glacier but has had to return to base due to the failing light and increasing winds.
It is understood that the rescuers then found that they had a 90m climb to where the party is believed to be. All will be spending a night on the glacier. There is a medic in the rescue group. I do know a this stage if they plan to reach the two stranded persons tonight.
There have been another four rescuers established at another camp further down the valley.
