It's an Inukshuk

(ee-nook-shook or ee-nook-sook) is an Inuktitut word that means to look like a person (an Inuk). It is a stone cairn which has been used by the Inuit people to mark high points of land, good hunting and fishing spots or the way home. Inuit have been building Inuksuit (ee-nook-soo-eet / plural) for thousands of years. It is a symbol of trust and reassurance for those who travel across the vastness of the Arctic.
