interesting that Guy Waterman, the father of John Mallon Waterman who perished attempting to climb Mt. Denali as recounted by Krakauer in his book, committed suicide by climbing a mountain in 2000 and freezing to death.

Another son of Guy (John's brother) also committed suicide per Amazon reviewer.
