At Port Harmon you can view the cliff called Indian Head. Most of the rocks in the cliff are a type called anorthosite. Anorthosite is found only in a few places on Earth. (It is more common on the Moon). All known examples are very old. These are about 1,000 million years old, among the oldest in the province. The anorthosite of Indian Head formed very deep below the ancient supercontinent Rodinia – about 30 or 40 km below the surface. Above them was a hugh mountain range, now all worn away.
