Haïdas
Hecate Strait, because it is so shallow, is especially susceptible to storms and violent weather. The Haida crossed the Hecate Strait to the mainland to plunder coastal villages to take slaves and booty. Only the Haida knew the real nature of the Strait's workings, and so could not be followed by the tribes of the mainland. Hecate Strait, therefore, was one of the main defenses of the Haida people from attack.
