The Monte Cristo history/outdoor reference by Harry Majors is excellent. A more detail account is authored by Philip R. Woodhouse, published by the Seattle Mountaineers. Perhaps these links should also be noted as an aid to understand the history of the area:
"After the first glass, you see things as you wish they were. After the second, you see things as they are not. Finally, you see things as they really are, which is the most horrible thing in the world."
--Oscar Wilde on Absinthe
