A field trip to Spanish Pyrenees

The Pyrenees are a collision mountain belt formed by the N–S convergence of the European and Iberian cratonic plates in the Santonian–Early Miocene time. it is a range of mountains in southwest Europe that forms a natural border between Spain and France. Reaching a height of 3,404 metres (11,168 ft) altitude at the peak of Aneto, the range separates the Iberian Peninsula from the rest of continental Europe, and extends for about 491 km (305 mi) from the Bay of Biscay (Cap Higuer) to the Mediterranean Sea (Cap de Creus).
