Ailsa’s travel-themed photo challenge this week is Stone. For this I chose the beautiful and intriguing limestone landscape of Andalusia, between Ronda and Seville:
El Torcal (Paraje Natural Torcal de Antequera)
It is a nature reserve in the Sierra del Torcal mountain range located south of the city of Antequera. You need a good footwear to climb up the stones. It does get quite fresh up there, thus take a jacket with you! We avoided the souvenier shop and restaurant, but even that is taken care of!
Not being a geologist, I am referring to Wikipedia for more reference
The Jurassic age limestone is about 150 million years old and was laid down in a marine corridor that extended from the Gulf of Cádiz to Alicante between the present Atlantic Ocean and Mediterranean Sea. These seabeds were uplifted to an elevation of over 1300 meters during the Tertiary era, resulting in a modest mountain range offlat-lying limestone, which is rare in Andalucia. Later, a series of fractures, cracks and faults at right-angles (generally NW-SE and NE-SW) were exploited by erosion and produced the alleys between large blocks of limestone visible today. The blocks themselves have been subjected to both dissolution by water (karstification) and freeze-thaw splitting action which, working on the limestone’s horizontal beds, resulted in the various shapes visible today, many of which resemble, and have been named after, everyday objects such as the Sphinx, the Jug, the Camel, the Screw, etc. Other flat surfaces have been karstified into rugged, rocky lands where travel on foot is difficult.
