Aerial reconnaissance will continue for a second day in the search for a Sydney mountaineer, who is feared dead along with seven companions in India's Himalayas.
Ruth McCance is missing along with British team leader Martin Moran, three men from the UK, two people from the US and an Indian liaison officer.
The eight adventurers were part of a 12-member expedition attempting to summit a previously unclimbed route up Nanda Devi East.

The trip was expected to take about 24 days.
The expedition's British deputy leader, Mark Thomas, remained at the second base camp with three others, but was in radio contact with the group of eight that pushed higher.
When Mr Thomas didn't hear anything after May 26 he went up to look for them and reportedly found a single unoccupied tent.
There was evidence of a large avalanche beyond that.
Indian Air Force helicopters made two reconnaissance missions on Sunday morning.
The first was to take photographs of the area for mountaineers from the Indian Mountaineering Foundation to examine and give advice as to where the group could be.
A second helicopter picked up Mr Thomas from the base camp and returned to the site where the group is believed to have gone missing from, IMF spokesman Amit Chowdhury told AAP on Sunday.
"Today's search has not hinted any results, we have not been able to spot any people, or any gear or any clothing," he said.

"But they've been able to see footsteps going to a certain point and then beyond that is the track of the avalanche. So that's the news, it's not looking too good."
Another aerial reconnaissance is planned for Monday.
Ms McCance's husband, Trent Goldsack, said the last time he heard from her was a text message a week ago, which said, "OK at base camp."

"They basically went dark after they left Delhi, but that was expected. She's done this stuff before," Mr Goldsack told the Sydney Morning Herald.
A rescue team of up to 20 people - including members of the Indian-Tibetan border police and the state disaster management force - left Munsiyari on Saturday morning local time, Mr Chowdhury said.
But it will take them at least three days to reach the avalanche site.
