the sherpas listed here were the climbing sherpas hired by rob hall's adventure consultants. there were many other sherpas working at lower elevations, who performed duties vital to the adventure consultants and mountain madness expeditions. most climbing sherpas' duties require them to ascend at least as high as camp iii or iv, but not all of them summit. the expedition leaders intend for only a select few of their climbing sherpas to summit. legendary sardar apa sherpa was scheduled to accompany the adventure consultants group but withdrew due to family commitments.
