The Yellow Band is a steep section of the Lhotse Face on the approach to the South Col, where the route to Everest’s upper camps becomes more than a line on a map: it must be cut, equipped, checked, and climbed. During the 1996 expedition it served as a critical passage between Camp III and Camp IV, a work site for the Sherpas and guides who installed fixed ropes, and a marker of the effort required to prepare for a summit attempt.

Position and Terrain

From Camp III, the route climbed the Lhotse Face toward the Yellow Band and then continued toward the South Col. Camp III itself had been carved into the sloping face, at an angle likened to a ladder leaning toward a second-story window. The Yellow Band lay above the camp on the route where climbers had to continue gaining height before reaching the South Col and the planned site of Camp IV.

The passage was consequential not simply because of its elevation but because it was a place where climbers relied on fixed ropes. From Camp II, the approach to Camp III took about three and a half hours for Anatoli Boukreev and the Sherpas travelling with him. Above Camp III, they continued onto the line toward the Yellow Band, where rope installation and maintenance consumed long stretches of strenuous work.

Route Preparation and Rope Work

On one climb from Camp III, Boukreev advanced in the lead while Ang Dorje belayed him and other Sherpas passed rope up the mountain. They worked at an even pace for almost five hours, reaching 7,550 meters just below the Yellow Band. The task linked the labor of several climbers: one person advanced along the route, another secured him, and others supplied the rope needed to extend the line.

The work continued on subsequent days. Boukreev checked earlier placements, making sure anchors were not creeping and tie-offs remained secure. He also removed old rope still attached to anchors, since a climber might otherwise clip into a line that was weak or improperly anchored. Working with Ang Dorje, he helped push the route higher above the Yellow Band. Sherpas pulled older ropes from the snow, examined their condition, kept those that still appeared sound, and fixed usable and new rope to anchors as they climbed.

The route preparation had consequences beyond the safety of an individual passage. A cooperative agreement among Scott Fischer, Rob Hall of Adventure Consultants, Todd Burleson of Alpine Ascents International, Ian Woodall of the Johannesburg Sunday Times Expedition, and Makalu Gau of the Taiwanese National Expedition called for work on the ropes between Camps III and IV. Mountain Madness planned to send Sherpas rather than guides, but a competing need to establish Camp III and then give exhausted Sherpas a rest left the team short of workers for the joint effort. Boukreev was sent in their place. Mountain Madness accepted the assignment in part because not contributing could cost the expedition its position among the early teams attempting the summit; May 10 was already circulating as a possible summit date.

Acclimatization and the Move to Camp IV

The Yellow Band also marked a stage in the expedition’s gradual ascent. The acclimatization plan called for repeated climbs to increasing elevations, followed by descents and rest so that clients could recover and guides could assess their condition. The team’s first excursion reached the planned Camp I elevation of 6,100 meters without an overnight stay. Later trips included sleeping at Camp I and climbing toward the height where Camp II would be established, followed by a return to lower camp for recovery.

For climbers travelling from Camp III to Camp IV, the Yellow Band was the first notably strenuous section of the ascent. Henry Todd explained that climbers who intended to use oxygen generally put it on at Camp III before tackling the climb over the band, so they would not exhaust themselves on the way to Camp IV. This made the passage an operational threshold: it was where a carefully staged acclimatization climb also required decisions about effort and oxygen use.

The route plan for the final summit push depended on fixed ropes being ready above Camp IV as well. Climbers from the Fischer and Hall expeditions understood that their climbing sirdars, Lopsang Jangbu Sherpa and Ang Dorje Sherpa, would leave Camp IV ahead of the clients to install lines, so the following climbers would not have to wait. In practice, the Sherpas had not departed early to fix those ropes. Lopsang later said a climber from a Montenegrin expedition that had attempted and failed to summit the day before had told him the ropes were already fixed. Jon Krakauer questioned that account, noting that Lopsang and Ang Dorje left Camp IV carrying rope. Other interpretations in the book emphasize the uncertainty around what Fischer and Hall had been told. The dispute illustrates how summit plans could depend on assumptions about route preparation that were not shared or verified by everyone.

A Passage Within a Fragile Network

The Yellow Band’s significance is tied to the wider organization of the climb. Rope, oxygen, camps, and radios were not incidental equipment: they were the means by which separate teams could move, prepare a route, and respond to trouble. The expedition’s older two-way radios drew criticism from Martin Adams, who considered them antiquated and inadequate. On summit day, the limits of communication were compounded by a relay system in which messages passed through several Sherpas and could arrive incomplete or delayed. The route’s fixed lines could guide climbers physically, but they could not ensure that the people responsible for the climb had the same information.

The broader account also shows the costs of relying on an overstretched support structure. On another expedition, the Sherpas were not fully under their guide’s control, could not keep pace with the work required to establish camps and fix lines, and a plan to establish a high Camp V had to be abandoned after resistance within the team. On Mountain Madness, concern about the strength and leadership of the Sherpa team arose alongside worries about exhausted workers, delayed camps, and the work still needed on the route. These accounts place the Yellow Band within a larger pattern: safe passage depended on labor, equipment, rest, and cooperation, while progress toward a summit could put pressure on each of them.

As a location, the Yellow Band therefore carries both a literal and an organizational meaning. It is a section of steep terrain that climbers had to cross on the way to the South Col, but it is also a point at which plans became material: rope had to be brought up, anchors tested, old lines removed, and climbers’ strength managed. The climb through it reveals how much an expedition’s apparent forward motion depended on coordinated work—and how vulnerable that motion became when equipment, labor, or communication fell short.
