There is a a book about this tragedy
called Young Men and Fire by Norman Maclean
(he also wrote A River Runs Through It)
and there have been several fire fighting rules
formed based on the Mann Gulch incident.

Norman's Son has also researched the more recent
fire fatalities in Colorado...the 1994 Storm King fire.

His son John now conducts fire
training courses based on the information he
learned from these fire investigations.
