This distinctive physical map of the Indian Ocean floor appeared in the October 1967 issue of National Geographic. The detail of such submarine terrain as continental shelves, basins, fracture zones and the mighty Mid-Oceanic Ridge is stunning. A true work of art, and a wonderful companion to the ocean floor maps of the Atlantic (1968), Pacific (1969), and Arctic (1971).
