A fictional floating mountain featured in James Cameron's 2009 film Avatar. Located on the moon Pandora, it is where avian species known as Ikran primarily roost.
It is customary for the members of the Na'Vi tribe to go to Hallelujah Mountain and "bond" with one of the Ikrans in the form of rite of passage.
An element known as Unobtainium is what make Hallelujah Mountain and its surrounding mountains float.
In January 2010, it was announced from China that one of its mountain, which was said to be an inspiration for Hallelujah Mountain, had been renamed "Avatar Hallelujah Mountain" (阿凡达-哈利路亚山) in honor of the film.
Avatar is serious business.
