Leaf Mountain Township, organized January 7, 1874, was at first called Dovre Fjeld, for the mountainous plateau of that name in Norway. It was renamed March 18, 1874, for its Leaf hills or “mountains,” a belt of conspicuous moranic drift hills. Their aboriginal name, given by Gilfillan as Gaskilbugwudjiwe, translated as “Rustling Leaf mountain,” was applied alike by the Ojibways to these drift hills.
