More than 500 foreign adventurers have converged on Nepal’s Mount Everest this spring, creating long queues in the high‑altitude Death Zone as they race to summit during a brief weather window.. Images from base camp show climbers in a snaking line between Camp III and Camp IV, a stretch where supplemental oxygen and split‑second decisions are essential for survival.

Nearly 500 permits issued for the 2024 Everest season

According to the Nepali government, almost 500 foreign climbers received permits to attempt Everest this year, a figure that eclipses pre‑pandemic averages. The influx arrived at base camp in early May, where weeks of acclimatisation have already begun. The surge reflects a post‑COVID rebound in adventure tourism and a belief that improved logistics make the climb “safer” than ever.

Traffic jams choke the Death Zone between Camp III and Camp IV

Explorers Web reports that the bottleneck is forming on the notorious stretch between Camp III and Camp IV,a 2,000‑meter corridor known as the Death Zone. Climbers must move quickly because exposure to thin air and sub‑zero temperatures can cause rapid physiological decline. The queues, some stretching for hundreds of metres, force climbers to wait for oxygen bottles and rope teams, increasing the risk of altitude‑related illness.

Icefall route opened amid serac crack warning from SPCC

The Sagarmatha Pollution Control Committee (SPCC) opened the Khumbu Icefall on April 29, but simultaneously issued a stark alert: “The serac has multiple cracks and may collapse at any time.” Elite guides, dubbed “Icefall doctors,” are tasked with clearing the route, yet the warning underscores how a single rockfall could trap dozens of climbers in the already‑crowded zone.

Experts warn melting glaciers could amplify risk

Climate scientists and veteran mountaineers alike cite accelerating glacier melt as a new variable in Everest safety. U.N. Secretary‑General António Guterres visited the Himalayas in 2023 and warned that “devastating levels of melting” threaten both routes and the stability of high‑altitude camps. Jon Krakauer, author of *Into Thin Air*, notes that while equipment and support have improved, “mass‑casualty incidents remain a tremendous risk.”

Will supplemental oxygen supplies keep pace with the crowd?

One unanswered question is whether the logistics chain for supplemental oxygen can meet demand amid the traffic jam. Expedition operators have not disclosed exact cylinder inventories, and no official figure has been released on potential shortages. If supplies run low, the already‑tight window for a safe summit could close dramatically.
