Some unknown artist(s) built several Inuit rock sculptures in a small inlet on the Ottawa river, a sculpture garden if you will. These remained intact over the years, and more appeared to be added each year.
Update: thanks to +Paul Cullum
who pointed out that the artist is actually John Ceprano (http://www.jfceprano.com/
), and that his rock arts are in fact not Inukshuks, and are not derived from Inuit rock sculptures.
