The team has collected the scattered parts of the climber’s body. A Fishtail Air helicopter has also been sent to Camp II to conduct a long line rescue, according to a source at base camp.

This is the first death of the season on Mt Everest.

Swiss alpinist Steck and Tenzing (Tenji) Sherpa headed to Khumbu region to attempt to climb Mt Everest by never repeated West Ridge/Hornbein Couloir route without using supplemental oxygen in the spring climbing season. They also set out a plan to make a descend to the South Col before taking the once climbed direct route just below the Lhotse Face to obtain that summit record.

“Quick day from base camp up to 7,000 m and back. I love it, it’s such a great place here. I still believe in active acclimatisation. This is way more effective than spending nights up in the altitude!,” the climber posted on his Facebook page on April 26.

Steck, who won two Piolet d'Or awards in 2009 and 2014, is also famous for his speed records on the North Face trilogy in the Alps. He won his second award in 2014 after making the first solo ascent of Mt Annapurna. Steck who was the first recipient of the Eiger Award for his mountaineering achievements in 2008, also completed his 82 Summits project, ascending all 4000 m peaks in the Alps, in 61 days in 2015.

According to him, he spent two nights in camp II. His Facebook post on April 24 indicated that Tenzing suffered frostbite a few days ago.  “Hopefully Tenzing Sherpa frostbite is getting better soon so we can be together on the mountain again.”

In 2013, an ambitious plan to summit Mt Everest was foiled after Steck along with Italian alpinist Simone Moro and Jonathan Griffith engaged in a heated confrontation with rope fixing Sherpas.

Last year, Steck and his German climbing partner, David Göttler, spotted the bodies of Alex Lowe and David Bridges who died in an avalanche on Mt Shishapangma in 1999.

According to the Department of Tourism, Ueli Steck was a leader of one the Everest expeditions locally managed by Kathmandu-based Royal Orchid Treks and Expedition.

Steck was not only the greatest alpinist in the world but also a good friend of Nepal, senior Captain with Manang Air Ashish Sherchan who flew the alpinist to different locations on Mt Everest recently remembered.

“I can’t express what a loss this is to the mountaineering community, Ueli loved Nepal, Everest and the Himalaya,” renowned climber Alan Arnette commented from Colorado.

According to Durga Datta Dhakal, Director at the Department of Tourism, Ueli's body was airlifted to Lukla.
