More than six decades have gone by since Sir Edmund Hillary and Tenzing Norgay etched their names in history as the first individuals to successfully summit Mount Everest. Despite the passage of time, the mountain continues to captivate adventurers. While tales of triumph and, more recently, heartbreaking tragedies dominate the narrative, numerous intriguing details about Everest remain widely unknown.
10. Spiders on the Mountain
Even at extreme altitudes, where oxygen is scarce, spiders still find a way to thrive. Euophrys omnisuperstes (“standing above everything”), commonly referred to as Himalayan jumping spiders, inhabit cracks and crevices on Everest’s slopes, earning them the title of one of the planet’s highest permanent dwellers. Climbers have observed them at elevations as high as 6,700 meters (22,000 ft).
These small spiders survive by feeding on windblown insects carried up the mountain by fierce gusts. They are among the very few creatures that live permanently at such heights, alongside a handful of bird species. Additionally, during the infamous 1924 British Everest expedition, several unidentified grasshopper species were collected and are now exhibited in the British Natural History Museum.
9. Two Climbers Have Summited Everest 21 Times
Two Sherpas, Apa Sherpa and Phurba Tashi, share the record for the most ascents of Everest. Both have achieved the remarkable feat of reaching the summit 21 times. Phurba accomplished this three times in just 2007, while Apa has summited the mountain nearly every year from 1990 to 2011.
Apa has witnessed significant changes on Everest due to global warming over the years. He has expressed concerns about melting snow and glaciers, which reveal more rock and make climbing increasingly difficult. He also fears for the safety of Sherpas, having lost his own home to a flood caused by melting glaciers. Apa has used several of his climbs to highlight the impact of climate change.
8. The Highest Altitude Fight in the World
Climbing Everest isn’t always the peaceful achievement many envision. In 2013, climbers Ueli Steck, Simone Moro, and Jonathan Griffith were involved in a fierce altercation with Sherpas after reportedly disregarding instructions to stop their ascent.
The Sherpas claimed the climbers disrupted their work and triggered an avalanche that struck other Sherpas setting up ropes below. The climbers refuted these claims, leading to a physical confrontation. The Sherpas attacked them with kicks, punches, and rocks, and Moro recounted that one enraged Sherpa even threatened his life.
The situation could have escalated further, but American climber Melissa Arnot advised the trio to retreat to basecamp before the Sherpas formed a mob and turned deadly. Following the clash, a Nepal army official mediated, and both parties signed a peace agreement to resolve the conflict.
7. A History Spanning 450 Million Years
While the Himalayan Mountains emerged 60 million years ago, Everest’s origins trace back much further. The limestone and sandstone at its peak were once part of sedimentary layers that lay beneath the ocean 450 million years ago.
Over millions of years, rocks from the ocean floor were compressed and thrust upward at a rate of up to 11 centimeters (4.5 in) annually, eventually forming the towering peak we see today. The upper sections of Everest now hold fossils of marine life and shells, remnants of its ancient underwater past.
Explorer Noel Odell first identified these fossils within Everest’s rocks in 1924, confirming the mountain’s submerged history. The initial rock samples from Everest were collected by Swiss climbers in 1956 and later by an American team in 1963.
6. Controversy Over Its Height
What is the exact height of Mount Everest? The answer depends on which side of the border you ask. China claims the peak stands at 8,844 meters (29,016 ft), while Nepal insists it is 8,848 meters (29,029 ft).
China’s stance is that the mountain’s height should be based solely on rock, excluding the snow at the summit. However, the global standard for measuring mountain heights typically includes the snow layer.
In 2010, the two nations reached a consensus, officially recognizing the height as 8,848 meters.
5. It’s Still Growing
Recent measurements suggest that both China’s and Nepal’s estimates of Everest’s height might be inaccurate.
In 1994, a research team found that Everest grows by about 4 millimeters (0.16 in) annually. The Indian subcontinent, once a separate landmass, collided with Asia to create the Himalayas, and the tectonic plates are still shifting, causing the mountains to rise further.
In 1999, researchers from the American Millennium Expedition installed a global positioning satellite device near the summit to track its growth. Their precise measurements, aided by modern technology, prompted the official height of Everest to be updated to 8,850 meters (29,035 ft). While tectonic activity in some areas reduces the mountain’s height, the overall trend indicates it is still rising.
4. It Has Multiple Names
While the world knows it as “Everest,” Tibetan locals have referred to the mountain as “Chomolungma” (or “Qomolangma”) for centuries, meaning “Goddess Mother of Mountains.” Additionally, the Nepalese call it “Sagarmatha,” translating to “Forehead in the Sky,” and it is a central feature of Nepal’s “Sagarmatha National Park.”
The mountain was christened “Everest” after British surveyor Andrew Waugh could not identify a widely recognized local name. After examining maps of the region and failing to settle on a name, he honored Indian Surveyor General George Everest, who led the British team that first mapped the Himalayas. Despite Colonel Everest’s objections, the British officially renamed “Peak XV” to “Mount Everest” in 1865.
3. It’s Not the Tallest Mountain
While Mount Everest is the highest point above sea level, Mauna Kea, a dormant Hawaiian volcano, is technically the tallest mountain on Earth.
Everest’s peak sits at a greater altitude, but Mauna Kea surpasses it in total height. Although Mauna Kea rises only 4,205 meters (13,796 ft) above sea level, it extends an astonishing 6,000 meters (20,000 ft) below the ocean’s surface. From its base on the seabed, it measures 10,200 meters (33,465 ft), making it nearly a mile taller than Everest.
In reality, depending on the measurement criteria, Everest is neither the tallest mountain nor the highest point. Chimborazo in Ecuador, standing at 6,267 meters (20,661 ft) above sea level, claims the title of the highest point from Earth’s center. This is due to its location just one degree south of the equator, where the planet’s bulge places Ecuador’s sea level farther from the core than Nepal’s.
2. The Most Polluted Mountain in the World
While countless photos capture climbers ascending Everest, few reveal the aftermath of their journeys. The mountain is marred not only by the remains of climbers but also by an estimated 50 tons of garbage, with more accumulating each climbing season. The slopes are littered with discarded oxygen tanks, climbing gear, and significant amounts of human waste.
Since 2008, the Eco Everest Expedition has been addressing the mountain’s waste issue, collecting over 13 tons of garbage to date. In 2014, the Nepalese government introduced a regulation requiring climbers to bring back 8 kilograms (18 lb) of waste during their descent or forfeit their $4,000 deposit.
Artists involved in the “Everest 8848 Art Project” have transformed 8 tons of trash, including discarded tents and beer cans, into 75 artistic creations. Over two spring expeditions, 65 porters hauled down the waste, which artists then converted into sculptures to raise awareness about the mountain’s pollution problem.
1. A Crowded Climb
Despite the fact that climbing Everest requires a significant financial investment, the number of people attempting the summit has never been higher. In 2012, German climber Ralf Dujmovits captured a striking photo of a massive line of climbers waiting to reach the top. Ralf had decided to retreat at the South Col due to bad weather when he noticed the exceptionally long queue.
On May 19, 2012, climbers faced a two-hour delay at a key point near the summit. Within just half a day, 234 people reached the peak, but tragically, four lost their lives, sparking serious concerns about the climbing process. That year, Nepalese experts installed a new fixed rope to reduce crowding, and discussions have even taken place about adding permanent ladders.
