The Hallelujah Mountains are comprised of mountains floating in the air above Pandora. The mountains, which often collide in midair and are called the Thundering Rocks by the Na'vi, are suspended by the magnificent attraction between the moon of Pandora and her mother planet, Polyphemus. These great floating stones are forested, sometimes connected by great cable-like bridges of vegetation and often have majestic waterfalls cascading from their sides. The “floating” reality of the mountains became apparent after a science team measured the prodigious magnetic fields that supported the mountains — it is attributed to the massive unobtanium deposit that was found. Its superconducting properties provided the first clue to help unravel the mystery of the Floating Mountains.
