Concern over Boyan Petrov

Boyan Petrov some weeks ago in Kathmandu

The most successful Bulgarian high altitude climber, Boyan Petrov, has been missing for several days on the eight-thousander Shishapangma in Tibet. This was confirmed today by his partner Radoslava Nenova on Facebook. According to her, a search for Petrov is to begin tomorrow. Previously, the team of the Hungarian climber David Klein reported that the 45-year-old Bulgarian had set off on 29 April for a solo attempt without bottled oxygen. On 3 May, last Thursday, Petrov was seen from base camp by telescope at the level of Camp 3. On Saturday, an Ukrainian and three Sherpas reached Camp 3 at about 7,400 meters and found Boyan’s semi-open tent with his sleeping bag, covered in snow. Obviously, Petrov had left for the summit.

Ten eight-thousanders without breathing mask


Petrov wished to scale his eleventh eight-thousander, the 8,027-meter-high Shishapangma, like the ten others before without breathing mask. Subsequently he wanted to move on to Everest. In the past two years alone, Boyan had succeeded five summit successes on the highest mountains in the world: In 2016 on Annapurna, Makalu and Nanga Parbat, in 2017 on Gasherbrum II and Dhaulagiri. Petrov works as a zoologist at the National Museum of Natural History in the Bulgarian capital Sofia and is a specialist in wildlife in caves. The climber has survived cancer two times. As a result of chemotherapy, Boyan has been suffering from diabetes for 18 years.
