Location
Mistastin crater, aka Kamestastin, It lies within the traditional hunting grounds of the Mushuau Innu First Nation. The presence of cubic zirconia around the crater rim suggests that the impact generated temperatures in excess of 43% that of the surface of the Sun and the highest crustal temperatures known on
