Several of the islands that make up the Bonaparte Archipelago are visible in this view of the rugged north coast of Western Australia. Prince Regent River, the exceptionally straight dark feature (lower right quadrant) that is oriented southeast-northwest, flows into St. George Basin, the body of water which lies upper right of center almost surrounded by land. The river’s linearity indicates that it is located along a major fault that extends into the Indian Ocean at Brunswick Bay (top) The body of water along the lower left side of the picture is an inlet of Doubtful Bay.
