Karst: A landscape formed as soluble bedrock dissolves, producing features such as caves, sinkholes, and underground drainage. El Torcal is a classic karst landscape shaped chiefly in limestone.
Mesozoic: The geological era lasting from about 252 to 66 million years ago, between the Paleozoic and Cenozoic eras. The limestone strata at El Torcal formed during this broad interval of Earth history.
El Torcal de Antequera Nature Reserve: A protected area in Andalusia, Spain, encompassing the distinctive limestone massif of El Torcal. Its protected status guides conservation and public access across the landscape.
Tornillo del Torcal: A distinctive, screw-shaped limestone formation in El Torcal de Antequera, Spain. Its stacked, rounded layers exemplify the landscape’s unusually sculpted rocks.
Limestone: A sedimentary rock composed mainly of calcium carbonate, commonly formed from marine organisms and seafloor sediment. Its limestone strata supplied the soluble rock from which El Torcal was carved.
Tethys Ocean: An ancient ocean that lay between the northern continents and the southern supercontinent Gondwana. Marine sediments accumulated in the region when an ancient sea covered it.
Hiking: Walking over natural terrain for recreation, exercise, or exploration. Marked routes let visitors experience the rock formations without leaving established paths.
Antequera: A city in Andalusia, Spain, situated north of Málaga and near El Torcal de Antequera. The city is the nearest major settlement and gives the massif its regional setting.
Chemical weathering: The breakdown or alteration of rock through chemical reactions with water, air, or dissolved substances. Rainwater dissolves calcium carbonate and gradually enlarges cracks in the limestone.
Sedimentary rock: Rock formed through the accumulation, compaction, or chemical precipitation of sediments. El Torcal’s limestone began as sediment deposited on an ancient seabed.
