Found out the oldest rock on Earth is in Canada and it's over 4 billion years old

I was reading an old geology textbook from the library and it said the Acasta Gneiss in the Northwest Territories is about 4.03 billion years old. That number just stuck in my head. I always figured the oldest stuff was way younger. Makes you think about how much the planet has changed since that rock first formed. Anyone know of a good documentary that shows that area?

Your buddy tried to find it? That seems like a huge waste of time for a boring old rock.
