The most extraordinary thing about Chilean coal is where the miners had to go to reach it. At Lota, on the Arauco coast, the tunnels did not just plunge into a hillside.

Men spent their working lives down there, in galleries propped with eucalyptus timber, with the weight of the sea overhead. The shaft was nicknamed El Chiflón del Diablo, the Devil's Draught, and it is remembered today as the only undersea coal mine of its kind in the world.

Large-scale coal mining in the Arauco Basin came to an end in the 1990s, and the great undersea works at Lota fell silent. Other deposits had their day too, from the small mines of the Los Ríos region with names like Catamutún and Pupunahue, to the far southern Magallanes pits ne...
