Lute Jerstad, 61, who in 1963 became one of the first Americans to climb Mt. Everest, died of a heart attack on Saturday in Tukla, just 500 feet (150 meters) short of the 15,000 feet (4,545 meter) peak of Mt. Kalapatar.
Alison Hargreaves is the first woman to have made the climb up the Everest with no artificial oxygen.
