From a geological point of view, Spain is extremely varied with sites as old as 600 million years and showing rare examples of the planet’s evolution. Two parallel projects now seek to document this national heritage. The aim of the first project is to include 144 Spanish sites on the Unesco world list of outstanding geological sites. The second project seeks to create a Spanish catalogue of geological sites of interest, which will then allow them to be protected by law, and include sites in Abella, Isona and Camarasa, in Lérida; Punta Aitzgorri in Zumaya (Basque Country), and the Sorbas reefs in Almería. Other interesting places to be protected include the amber deposits in Peñacerrada, El Soplao, in Cantabria, the carboniferous forest of Verdeña, and the ichnite (dinosaur track) sites found in a number of areas.
