Impact Crater

The Impact Crater is the final location visited by Samus during the events of Metroid Prime. It was created when a Leviathan from Phaaze impacted Tallon IV. It is the only known location of Orange Phazon. Lumigeks, and Fission Metroids are also located here. Also this is where Samus faces Metroid Prime, the final boss of the game.

The Impact Crater was sealed by the Chozo, using the twelve Chozo Artifacts and the Artifact Temple. This served to slow the spread of Phazon over Tallon IV.
