"To climb or not?"

High in the Himalayas, hundreds of climbers from around the world were reeling from the avalanche that swept through Qomolangma base camp in a few terrifying moments when the earthquake struck at around midday on Saturday.

Many Nepalese sherpa mountain guides had descended to their homes and villages to see if loved ones were safe.

Foreign mountaineers, meanwhile, were divided on whether to continue their pursuit of scaling the surrounding peaks in the event their local guides returned to lead them.

"For me personally it's probably too early to say how I feel about that," said Canadian Nick Cienski, who is attempting a record ascent of six 8,000-meter peaks this calendar year.

"I wouldn't want to continue if it made anybody uncomfortable to continue, sherpas included in that."

Romanian climber Alex Gavan, who had microblogged his eyewitness account of the avalanche and its aftermath, said he had left Qomolangma base camp to help the earthquake relief effort.

"The time is not for climbing now, but for helping Nepali people," he posted on Twitter on Monday.
