If you saw the movie Avatar on the big screen, you were more than likely awed by the 3-D spectacle of the planet Pandora.

For many, the most spectacular location on the fictional planet is the Hallelujah Mountains - giant, square-sided, floating rocks shrouded in mist, covered with rich vegetation and fast-flowing waterfalls dropping away into nothingness, around which flying reptiles and futuristic military aircraft do battle.
