Proclaimed a National Historic Site of Canada in 1976, local indigenous people believe that this is an entrance into the spirit world and that the Spirits actually speak to them from this location. They call it Kinoomaagewaapkong, which translates to "the rocks that teach".The petroglyphs are carved into a single slab of crystalline limestone which is 55 metres long and 30 metres wide. About 300 of the images are decipherable shapes, including humans, shamans, animals, solar symbols, geometric shapes and boats.
