The story
About 5.3 million years ago the Mediterranean had nearly dried out. Then the Atlantic broke through here and refilled it. The myth says Heracles split the mountain. 14.4 km is the width of the water, and real crossings swim further because of the currents. Source: Garcia-Castellanos et al. 2009, Nature.
