Pico do Fogo is a cone of 2,829 metres in Cape Verde, the highest ground in the country, and it stands inside a caldera nine kilometres across whose floor people farm. The Bordeira, the caldera's western wall, draws a thousand-metre cliff around half the horizon, and the sense of standing inside something enormous never quite leaves you. The eastern side is missing. About seventy-three thousand years ago that flank slid into the Atlantic, and the wave it raised struck the next island, fifty-five kilometres away. Inside, the floor is broken volcanic rock that crunches and rings underfoot, some of it only a few years old. The vines go straight into the black sand and lapilli, the only grapes grown in any quantity in Cape Verde. They make Manecom, the dark, sweet, faintly smoky wine of Chã, poured in the village cellars.
The climb starts in the dark. Guides leave the village around four in the morning, because the ash slope is kinder cool, and it takes you four hours to the rim. Up there the crater opens 500 metres wide and 150 deep, fumaroles venting along its edge and the air turning sharp with sulphur, the island and the Atlantic laid out below you. Going down is the payment for it. The ash is deep enough to run, every stride sinking in and carrying you several metres, so the whole grind uphill is gone in minutes. Back on the floor, the 2014 lava stopped in Portela and Bangaeira with houses half inside it. Roofs and door lintels still surface out of the black rock, and the new homes stand a few metres away. There is somewhere else for these families to live. After an earlier eruption the government built them housing down at Monte Grande, and it stands almost empty, because it is too far from the caldera to farm from day to day. So after 2014, as after 1995, they rebuilt on ground that had just been declared too dangerous to build on, and put the winery up again with them.
