While admiring a landscape, we may see trees or animals, the fading colours at sunset, the appealing shaped clouds… but we rarely pay attention to rocks. Under this premise, Alex Nogués wisely guides us through the mysteries of Geology. And we greedily follow him as we need to find an answer to the question: what are a million oysters doing on the top of a mountain?
