Cultural Artifact

My artifact is definitely an example of cultural material because it's a national monument. My artifact is the the great Mt. Rushmore which has the faces of four founding fathers of the nation's history. Some of the design aspects include the faces in a smooth detail facing different ways as if they are watching the nation. Their faces are also carved into the top of the mountain which makes it visible from a further distance. The faces are in an order, why? Is it because that's the order is importance to the country? Questions that I'll uncover in the design project. I would consider this artifact as a cultural one, but maybe a sub cultural idea could be that if political measure. Being these are presidents and have a lot to do with the nation and government it fits into a political sub category.
