Anurag Maloo, an Indian climber who was missing for days, has been found alive and rescued by renowned Polish climber Adam Bielecki from a Mount Annapurna crevasse in Nepal.

Maloo, a 34-year-old entrepreneur and experienced mountain climber, is on a quest to climb all 14 peaks above 8,000 meters and the seven highest points in all seven continents. The mission is aimed at creating awareness about the United Nation's Sustainable Development Goals, according to NDTV.

The Indian climber went missing Monday as he made his way down Nepal's Mount Annapurna, the 10th highest mountain in the world. The mountain's treacherous terrain is known for giving hikers a challenging climb.

A search for Maloo began after the climber went missing at around 6,000 meters (19,600 feet) while descending from a camp.

"He had gone to scale Mt Annapurna peak and was at Camp III. Due to his health condition, he was asked to descend instead. While coming down, he slipped and fell in a crevasse between Camp III and Camp II," his father, Om Prakash, told the Indian Express.

The ground search and rescue team looking for Maloo included Bielecki and his friend as well as six Sherpa climbers led by Chhang Dawa.

Maloo was found Thursday morning in a 300-meter crevasse. His rescue was captured in a video, which has since made rounds on social media.

"His health is very critical. Doctors are looking after him," said Thaneswar Guragain, the general manager of Seven Summit Treks, the mountaineering company that led the search operation.

Maloo was transported to a hospital in Nepal's Pokhara and received medical attention.

Amit Chowdhury, a board member at the International Climbing and Mountaineering Federation, said climbers have a chance of surviving if they fall into a crevasse and don't sustain serious injuries.

"A crevasse is warmer and well protected from wind. So if he was not badly injured, it's not unusual that he survived in a crevasse," Chowdhury told BBC News.

Maloo's rescue took place in the same week that saw another climber losing his life in a separate incident on Mount Annapurna. The well-known Irish climber, Noel Hanna, 56, died Monday while returning from the summit.

Another Indian climber, Baljeet Kaur, was also found alive this week after falling ill and surviving harsh conditions on his way down the mountain.
