The woman was tramping on the glacier when she fell into the crevasse about 3pm yesterday.
Her fellow German climbing companion, Helmut Lachmann, a 55-year-old doctor, managed to reach her, secure her from slipping further into the crevasse and making splints for her before heading out to raise the alarm.
A three-man team from South Westland Alpine Cliff Rescue were flown by helicopter into the region.
