Premise: 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.
Hypothesis: Alison Hargreaves is the first woman to have made the climb up the Everest with no artificial oxygen.
