What's the next step after the oldest rock on Earth? Today, we'll move the story forward 200 million years and 1,000 miles. The time: 3.8 billion years ago... or maybe much older (March 3 on the Earth Calendar). The place: Nuvvuagittuq (noo-voo-ah-git-took), Quebec, Canada, in the lands of the Inuit. In this episode, we'll learn how this seaside outcrop was found and the ongoing debate about its' exact age. Depending on who you talk to, these are either the second-oldest rocks on Earth, or almost as old as the Earth itself.
