CATALYST PLANET - On Top of the World: A View of History and a Groundbreaking Climb From Mount Everest

Every year, hundreds brave frost, cliff and hypoxia to ascend the world’s tallest peak.

In 1953, Sir Edmund Hillary made history by being the first to ascend Mount Everest. His journey was a significant departure from the origins of rock climbing, the earliest evidence of which is found in the remains of cliffside dwellings by Native Americans and archaeological burial caves in Mustang, Nepal.

Today, mountaineering has become a popular competitive sport and means of exploring the natural world, with about 800 people attempting the dramatic climb to Everest’s summit each year. Expeditions are reliant on Nepal’s weather, with the best season typically occurring in April and May, before the monsoon, when avalanches are less common. September can also be a good month, but by October the onset of winter storms restricts climbing once again.

The ascent up Mount Everest utilizes a technique called siege climbing, in which climbers establish a series of camps along their route and sleep at the camp just below them, a technique that helps climber’s bodies more easily acclimate to the elevation.

Sherpas on Everest

Sir Edmund Hillary was not alone in his groundbreaking climb. In a fact often ignored in the histories, he was accompanied the whole way by Tenzing Norgay, a Nepali Sherpa mountaineer. As a mountain dwelling people of Nepal, Sherpa’s are known for their knowledge of the mountainous region, and have a long history of maintaining and cultivating the land. In a pattern that dates back to Norgay’s first ascent with Hillary, Sherpas today serve as guides to climbers on Mount Everest, while also working to maintain and safeguard the path.

In addition to acting as guides, Sherpa often provide life-saving assistance to straying climbers. In June 2023, a Nepali sherpa guided a Malaysian climber to safety after discovering the mountaineer in the thick of the “death zone”, facing temperatures dipping below -30 degrees Celsius.

The feats and history of Nepali climbers were extolled in the documentary 14 Peaks, which followed Nepali mountaineer Nimsdai Purja on his journey to summit all 14 of the world's 8,000-meter peaks in just seven months. Purja champions the Sherpa’s bravery and the irreplaceable role they play in maintaining Everest’s safety and accessibility for climbers, as well as their knowledge of and connection to the land.

The Costs of Ascension

The price of climbing Everest has grown steadily with its increasing popularity, and prices in 2023 range between $30,000 to $160,000. The staggering cost includes gear, food, supplemental oxygen, and base camp tents. The support of Sherpa’s is also an important consideration, with the cost of assistance ranging from $2,000 to $5,000.

The financial toll of ascending Mount Everest is commensurate with its physical brutality. The climb up is marked by harsh conditions. Altitudes above 25,000 feet (7,600 meters) are known in the climbing community as the “death zone”, and at 29,029 feet (8,848 meters) high, Mount Everest puts climbers in the thick of life-threatening danger. Some of the greatest threats at such altitudes relate to a lack of oxygen, or hypoxia, which leads to rapid breathing and an increased heart rate. High-altitude cerebral edema, or HACE, can also threaten climbers as the body responds to hypoxia with increased blood flow to the brain, leading to swelling that can bring on hallucinations, a loss of coordination, and the potential of a coma or death induced by brain herniation.

The cost of climbing Everest extends beyond the financial and physical impacts into ecological catastrophe. The world’s tallest summit is now derisively known as the “world’s highest garbage dump.” During the peak season, nearly 500 people make the hike to Base Camp on a daily basis, a physical toll that adds to the erosion of the natural land. Additionally, in the weeks during which they embark to the mountain’s summit, each climber creates roughly 18 pounds or eight kilograms of trash, which include tenting supplies, oxygen containers, and feces.

Clean Climbing

The Nepali government, alongside environmental agencies, has been working to preserve and clean up the mountain. In 1976, the Sagarmatha National Park was created as a means of protecting the mountain’s natural terrain and wildlife. It received recognition and protection as a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage site in 1979.

In 2019, the Nepali government launched a campaign to clean up 22,000 pounds or 10,000 kilograms of waste from Everest. Local authorities now require that each climber pays a deposit of $4,000, which is refunded after the individual returns back from their climb with an equal amount of waste as they are predicted to generate during their climb, approximately 18 pounds of garbage per person.

Along with local authorities, third party organizations are also working to preserve the future environmental health of Mount Everest. Launched in 201, the Mount Everest Biogas Project aims to create a solar powered system that turns human waste into fuel.

While irresponsible expeditions can lead to increased pollution, the action of climbing is in itself a kind of homage to the environment. Ascending Everest forces climbers to come face to face with the potential harm that human disruption can have on the environment, while reinforcing the importance of environmental protections and regulations.

With the future environmental health of natural wonders such as Mount Everest at risk, climbing and engaging with nature in an ethical, responsible, and sustainable way can create an important connection between people and the environment. An ascent to the world’s tallest peak can be not only personally enriching, but vital to public perceptions of and future investment in the environment.
