Ezhibiigaadek asin, written on stone, represents the collective memory of Great Lakes Anishinabek ancestors. Across Anishinabek aboriginal territory, certain places were sought for their spiritual power and significance and used for ceremony, teachings, and other sacred practices, many of which still continue today. Petroglyph sites hold valuable lessons and a distinct spiritual reference because they directly reflect Anishinabek oral history. Some ezhibiigaadek asin are said to contain very important information, including Creation and Prophecy Stories handed down from one generation to the next, while other symbols depict daily life and history, such as animal clans and celestial or seasonal events. The Anishinabek lived in small groups, usually by clan, and life followed the seasons as they hunted, fished, trapped wild game, harvested maple sugar, and used abundant food and plant medicines before European contact. Spirituality played an important role in Anishinabek life, and the petroglyphs illustrated the world and the universe as the people understood them. Some of the imagery found here also appears on sacred wiigwas, or birchbark scrolls, in earthworks or mounds, and in pictographs or rock paintings. These carvings and their teachings are helping twenty-first century Anishinabe understand their history, their present, and their future.
