You can find these all over the place up north.
Originally used to mark reference points, or as a marker for hunting grounds, or a food cache.... People mostly use them as decorative items now adays.
I believe that the Inukshuk were originally used by the native people of the artic region of North America.
Gotta check out my history books (aka - the internet ).
P.s. I went for a run today...... I hope I don't jinx myself when I say that it felt awesome!
