Kamestastin crater

Kamestastin crater (also known as Mistastin) is approximately 28 km in diameter. Located north of the 55th parallel, it was created some 36 million years ago by a violent asteroid impact. The island near the middle is the central uplift of the crater. Kamestastin lies within the traditional hunting grounds of the Mushuau Innu First Nation and is the closest thing we have to the Moon here on Earth. It contains a rock known as anorthosite, a rock that is rare on Earth, but covers about 80% of the lunar surface.  (Credit: Canadian Space Agency)
