Halfway between Montaña Colorada and Caldera de Los Cuervos is Montaña Negra, so-called because of its black colour. Enveloped with a blanket of dark volcanic ash, this volcano gives the impression that it emerged along with the others that appeared as a result of the series of eruptions in Timanfaya in the eighteenth century. But this is not the case; whilst other ancient volcanoes have lost their layer of ash due to erosion and are therefore lighter in colour, Montaña Negra is actually thousands of years old, but was ‘disguised’ by a layer of ash from the eighteenth century eruptions.

Despite the disastrous consequences of the Timanfaya eruptions, this ancient volcano in disguise did at least bestow an incredible gift upon the inhabitants of the area. When it rains, the water seeps through the layer of very absorbent ash and when it reaches the impermeable surface of the ancient mountain, it drips down its sides. Therefore, by digging through the petrified ash at the foot of the mountain, this water can be collected, even long after the rains have gone. This was a blessing at a time when thirst was persecuting the inhabitants of Lanzarote.
