10 million years in a walk at Costa Quebrada

Begin a fascinating journey through the geological history of the Costa Quebrada Geopark. Discover how cliffs, fossils, and beaches reveal 10-million-year-old secrets on an interpreted tour showcasing geology, landscapes, biodiversity, and culture.This interesting interpreted tour is the perfect opportunity to understand a landscape that, in addition to being beautiful, provides remarkable geological information. A walk along the Mataleñas coastal path, from El Sardinero to the Cabo Mayor lighthouse, holds the secrets of more than 10 million years of Planet Earth's geological history. We will learn about the origin of the materials that make up this part of the coast, the environment in which they formed, and coastal shaping.We will discuss ancient sedimentary environments where we will discover the fossil remains of a diverse invertebrate fauna. And it will be equally interesting to discover how the current coastlines are the result of multiple geological processes, primarily rising and falling sea levels in response to climatic changes or eustatic changes. The costal plain landscape reveals ancient sea levels from the geological past.You will discover a magnificent example of a retreating coastline controlled by lithology and structure. We will discuss the sedimentary environment in which Micraster, the fossil sea urchin that serves as the emblem of the Costa Quebrada Geopark, lived.And we must not forget the cultural and historical aspects of this environment, where the presence of numerous important military infrastructures can be seen.
