Images include animals eg, (caribou, moose, birds, snakes), anthropomorphic figures, hunting and fishing scenes, footprints and fingerprints, and ornamental designs that are also found on these people's clothes.
In addition to this traditional iconography, there are also images of European origin, such as firearms, churches and Christian designs, as well as beautiful representation of sailboats.
Several broad regions of rock art "style areas" have been distinguished, including the Maritimes, the Canadian Shield, the Prairies, British Columbia and the Arctic.
The Maritime provinces count many rock art sites that are usually attributed to the Mi'kmaq (MICMAC).
Radiocarbon dating at the Nisula site along Lac Cassette, Québec, indicated that the paintings were made about 2000 years ago.
The geographic distribution of rock art sites and the iconographic themes that are represented seem to indicate that carvings and paintings on the rocks of the Canadian Shield were produced by the ancestors of Algonquian populations (eg, OJIBWA, CREE, INNU).
The BC coast has many petroglyph sites, though the few pictograph sites are probably more recent.Here, there are no pictorial boundaries such as frames or groundlines, and it seems that there is no deliberate grouping of images.Aesthetic order is in accord with nature, and images are often integrated with the numerous hollows, crevices and seams of the rock itself.Although the majority of the images were traced with the finger, some could be executed with brushes made of animal or vegetal fibres.Petroglyphs are carvings that are incised, abraded or ground by means of stone tools upon cliff walls, boulders and flat bedrock surfaces.
