Wisedale said in a blog post on Wednesday that his teammates were "unbelievable" during the crisis.
"When the injured needed to be hauled into a makeshift medical tent – Rob [Bentley, the team's base camp manager] was there. I am very fortunate to be in the company of people I would go to war with," he said.
"We are currently out of base camp reflecting on what we have just survived. Our plans are not certain."
Johannesburg - South African climbers are still uncertain about whether they will tackle the highest peak in the world after an earthquake in Nepal left 5 000 dead, and resulted in an avalanche at the mountain.
Durban based climber Sean Wisedale and his teammates were at Mount Everest base camp when the avalanche hit the Nepali side of the mountain.
At least 17 people at the base camp died.
At 9 am yesterday a powerful ‘B3′ helicopter was dispatched from Kathmandu to evacuate a key member of our Sherpa crew – Angkami Sherpa. He was airlifted from 6300 meters on Mt Everest. ‘Kami’ was ascending to our Camp 2 at 6560 meters. Just above the Khumbu icefall he took an unfortunate fall and fractured his leg.
The route to Camp 2 has a number of complicated ice steps. He lost traction on one of them and fell, fracturing his right leg below the knee. Our team’s remaining Sherpas – Ongchhu, Phurba and Phursemba assisted by ‘splinting’ the injury and keeping Kami warm. Rob Bentley – Base Camp manager and Pasang Sherpa – Nepalese Liaison Officer were in constant communication and coordinated a risky high altitude rescue from Base Camp. Fishtail Air’s – Captain Reto (Swiss nationality) courageously navigated the helicopter into the Western Cwm, landed at the sight of the incident and airlifted Kami to the Helping Hand hospital in Kathmandu where he underwent surgery yesterday. He is recovering well. We are extremely grateful to Captain Reto of Fishtail Air and also to Kenwood Nexedge who provided the exceptional two way radio digital communication to coordinate the rescue.
