Where on Earth?

An Inukshuk (ee-nook-shook) is a pile of stones that represents a person, as pictured here in Nunavut, the new Canadian territory for the Inuit people. These structures are traditional landmarks in the Arctic region, where there are no trees and few distinguishing features to use for reference while traveling. The orientation of the stones may also give guidance by marking a trail on the tundra. Read about development in the Inuit territory.
