Petroglyphs

In the Hjemmeluft area on the southern shore of the Altafjord in northern Norway, just west of the town of Alta, Neolithic and Bronze Age petroglyphs were found in the autumn of 1972, ranging in age from 2000 to 6500 years.
Petroglyphs (from Greek πέτρος petros "stone" and γλύφειν glýphein "to carve") are representations worked into stone, which often show hunting and religious scenes from prehistoric times. Unlike rock art, a petroglyph is engraved, scraped, or pecked, and sunk into the ground.
