Inukshuk serve as Inuit signposts in the Canadian Arctic, and mark the highest point of land to aid in navigation or to assist in hunting, while some serve as sight lines to important and powerful places beyond the horizon.
An inukshuk is also shown on the flag of the Canadian territory of Nunavut, established in 1999, and is also found on the flag of the 2010 Winter Olympics to be held in Canada.
Toronto's Pearson International Airport broadcasts Y-Y-Z in Morse code for navigational purposes; this code inspired both the rhythms and title of the song "YYZ".
