"Namu is a Heiltsuk First Nation word meaning “place of high winds,” referring especially to the SE blasts that sweep over the 914-m Namu Range and give nearby Whirlwind Bay its name. Archeological excavations have revealed that Namu was used by [Indignous] people as a habitation site, at least seasonally, for 11,000 years or more and is this one of the longest continually occupied places in Canada. In 1893, Robert Draney built cannery at this spot and added a sawmill in 1911. The cannery was rebuilt and changed hands several times, eventually becoming one of the largest and most efficient fish-processing complexes on the BC coast... Namu Lk and Namu R derive their names from the community and harbour." (p. 417)
