Saint George Basin Out in the far north of Western Australia and only accessible by air or boat lies this beautiful blue harbour carved by the rising sea at the end of the last ice age out of the ancient rocks. The dark green areas are tidal flats filled with mangrove forests that are submerged by the twice daily high tides, while the rest of the bay is bounded by steep cliffs. At the lower right, the Prince Regent River joins the basin, and the whole area is part of a UNESCO Biosphere Preserve of the same name, now incorporated into a larger national park encompassing the whole Mitchell plateau.
