I recall a futile search on Whitney by CLMRG and Inyo SAR which ended in the discovery ten days later, by French mountain guides, of the young man's body on a ledge near the base of the Aiguille Extra. He was found with his camera still hanging from his neck. Cause: carelessness...not his age, health, or AMS...he slipped.
I remember this one, in September 1979. See pages
8 and 9. And, Bob, you are mentioned on page 7.
While he may have slipped, years later I learned details about this young man's life. They bring forth other possible explanations. Nevertheless, his death was very unfortunate, as was Mr. Kato's and all the others.
