Instead, when tourists pack up their relatively easily accessible camps, they leave behind tents, broken climbing equipment, empty gas canisters, and a whole lot of excrement.
"It is disgusting, an eyesore", Pemba Dorje Sherpa told AFP. He added, "There is just not enough monitoring at the high camps to ensure the mountain stays clean."Moreover, the melting ice caps - an indicator of climate change, has revealed tonnes of waste hidden in the mountain".
As the number of climbers on the mountain has soared - at least 600 people have scaled the world's highest peak so far this year alone - the problem has worsened.
Efforts have been made.
The Sagarmatha Pollution Control Committee (SPCC) has stated that the climbers in Nepal cleaned almost 25 tonnes of trash and 15 tonnes of human waste which is equivalent to three double-decker buses, during the year 2017.
But many rich climbers just don't care about the $4,000 deposit, when they're already shelling out so much for the experience, Pemda said. Compounding the problem, some officials accept small bribes to turn a blind eye, he said. In the last two decades, the Everest industry has boomed, exacerbating the rubbish problem.
This has sparked concerns of overcrowding as well as fears that ever more inexperienced mountaineers are being drawn by low-priced expedition operators desperate for customers.
Previously most climbers would take their own personal kit like extra clothes, food, a sleeping bag as well as supplemental oxygen.
Newbie climbers let their Sherpas schlep nearly all their gear - meaning the guides aren't able to carry trash down the mountain too.
Meanwhile environmentalists are concerned about the impact of the pollution on the water sources down in the valley. This becomes a festering pit of putrid grossness that the locals have to live with: during the monsoon season, it gets flushed downhill into their river. Ang Tsering Sherpa, former president of the Nepal Mountaineering Association believes that organising a dedicated rubbish collection team would solve this enormous problem. According to China's state-run Global Times report, a 30-strong cleanup team collected 8.5 tonnes of waste from the northern slopes of Everest last month.
"It is not an easy job. The government needs to motivate groups to clean up and enforce rules more strictly".
