Pico do Fogo stands 2,829 metres above the Atlantic, the highest ground in Cape Verde, and its cone rises from the floor of a caldera some nine kilometres across. That caldera is Chã das Caldeiras, and people farm it. The western wall, the Bordeira, rises in a cliff a thousand metres high; the eastern side gapes open to the sea. The floor between them, 1,700 metres up, is the only ground in the country that grows grapes in quantity. The vines go straight into black volcanic sand, and the wine they make, Manecom, is dark and sweet. The climb up the cone takes three to four hours from the village. It is 1,100 metres of loose ash and cinder, and the slope gives back half of every step.
In November 2014 the mountain erupted and buried the villages of Portela and Bangaeira, taking three quarters of their buildings, the school and the wine cellar. The flows ran on for seventy-seven days, and every one of the caldera's thousand people was moved out. By the time it stopped the lava had spread across more than four square kilometres of the floor. Within two years their people were rebuilding on the cooled lava, inside a zone where the government had just banned rebuilding altogether. That argument — a mountain against people who will not leave it — is the story of the place. Back on the caldera floor the 2014 lava lies bare and black, with roofs still half-swallowed beside new houses. That eruption came after a nineteen-year pause, and nobody in Chã speaks as though the mountain is finished.
