Mount Everest, the world’s highest peak at 8,848 metres, draws adventurers from all over. But the mountain on the Nepal-China border is fast becoming a dangerous place to visit even for the hardened mountaineer. The inherent risks were highlighted with a photograph by Nirmal Purja, a Gorkha ex-soldier. The image, which went viral and altered the manner in which people worldwide imagine what it is to scale Mt. Everest, showed a long queue awaiting a final tilt at the summit, with all the dangers such a wait holds. In the 2019 season, at least 11 climbers have died or gone missing, including four Indians. Experts have been calling for Nepal to restrict the number of permits. It awarded a record 381 for this spring each fetching $11,000 (climbing from the Tibet side is more expensive). On 22nd May, 200 climbers ascended the summit, a new record for a single day. Last year, 807 managed to reach the summit. In 2012, the United Nations estimated that there were more than 26,000 visitors to the Everest region, and this figure has grown manifold since then. Nepal officials argue that permits are not issued recklessly, and that jams such as this year’s near the summit are on account of spells of bad weather, which result in mountaineers being compelled to reach the summit within a narrow time frame. Waiting in sub-zero temperatures at rarefied altitude can be fatal--- this season’s deaths were mostly due to frostbite, exhaustion, dehydration and lack of oxygen.

This year’s drama has caught public imagination, as happened in 1996 when eight persons died in a single day amid an unexpected storm - events of and around that day were the subject of Jon Krakauer’s bestselling book ‘Into Thin Air’. The adventure industry that is built around the human desire to scale the peak has meant many amateurs take up the challenge, confident that support teams and specialized equipment will make up for their lack of adequate mountaineering experience. The fallout is that in case of a disaster not only are some of them unable to manage but they also hold up others, putting them in harm’s way. The commercial operations have led to the Everest being called the world’s highest garbage dump as many climbers discard non-critical gear, used oxygen cylinders, plastic bottles, cans, batteries, food wrappings, fecal matter and kitchen waste on the mountains. It is unlikely, however, that this season’s tragedies will deter future summiteers, as the hypnotic lure remains intact. But the authorities must learn from this year’s tragedies and work out an optimum number of climbers and strengthen safety measures.

If an amateur mountaineer is one who climbs mountains as a hobby, which word in the text, describes an experienced one.
