An inuksuk is a stone landmark or cairn built by humans, used by the Inuit, Inupiat, Kalaallit, Yupik, and other peoples of the Arctic region of North America.
These structures are found from Alaska to Greenland. This region, above the Arctic Circle, is dominated by the tundra biome and has areas with few natural landmarks.
The word inuksuk means “something which acts for or performs the function of a person”.
The inuksuk may have been used for navigation, as a point of reference, a marker for travel routes, fishing places, camps, hunting grounds, places of veneration, drift fences used in hunting or as a food cache.
