While this Canadian story has Glooskap as its hero, it could very easily have been the Anishinaabe legendary figure Nanabazhoo. (Because of different dialects and a lack of standardized written form of his name, it's sometimes Manabozho and other spellings -- and, yes, Longfellow created his own character of Hiawatha from him.) Canadian professor Cyrus Macmillan started with the Micmacs for Glooskap before moving westward in his collections of Canadian Wonder Tales (1918), the source of today's tale, and Canadian Fairy Tales (1922). Find all of his works, including those two, at the Internet Archive. Unfortunately for folklore lovers in 1923 he stopped collecting and his focus switched to the academic life of McGill University and politics.
That's my (and the Canadian) story and I'm sticking to it.
