Geology in El Torcal de Antequera Nature Reserve
El Torcal de Antequera is a truly outstanding example of the weathering of a type of rock that while fairly characteristic of the south of Spain, does not appear in such a unique and attractive form anywhere else in the region. Sedimentary rock rose from the Tethys seabed millions of years ago, forming El Torcal mountain range, which interestingly still exhibits some fabulous examples of imprints of fossilized ammonites.
The relative elasticity of the land mass produced a mushroom type form, with a flat top and steep sides. It is from this moment that the processes of erosion and dissolving begin due to a prolonged period of intense rain and the action of snow, present during many months of the year that not only fractured the rock but also then led to the producing of immense cracks and cavities.
