Here is a reference I copied from wiki.
inukshuk - is a human-made stone landmark or cairn used by the Inuit, Iñupiat, Kalaallit, Yupik, and other peoples of the Arctic region of North America. These structures are found from Alaska , United States to Greenland. This region, above the Arctic Circle, is dominated by the tundra biome and has areas with few natural landmarks.
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 to mark a food cache.
Varying in shape and size, the inuksuit have ancient roots in Inuit culture.
Back to me now. According to some photos I have seen some inukshuks were too large for one or two people to build alone, just by the height of the structure and weight of the stones. Sometimes they needed to be seen from quite a distance as a marker.
It isn’t uncommon around here to see a small inukshuk built in someone’s yard. Often not following traditional form very well. They have become a symbol of the far north, almost like an icon, stuck on everything relating to the north. Trinkets, souvenirs, etc.
