The Pyrenees are a massive mountain range located in southwestern Europe.

This range forms a natural border between France and Spain. The microstate of Andorra is also located within the range. The mountains stretch from the Cantabrian Mountains in the west to Cap de Creus on the Mediterranean coast.

They are part of a much larger geological division called the Alpine System. The highest peak in the entire range is Aneto.

The formation of these mountains began millions of years ago. The Pyrenees are older than the Alps. During the Paleozoic and Mesozoic eras, sediments were deposited in coastal basins. At that time, the area was located at the northwest margin of a landmass called Gondwana. Between 100 and 150 million years ago, the Bay of Biscay began to expand. This expansion pushed the land of Spain against France. This movement created intense compressional pressure on layers of sedimentary rock. This pressure caused the Earth's crust to uplift. This process continued until the Eocene Epoch.

Geologists divide the Pyrenees into three distinct physiographic sections. The first section is the Atlantic or Western Pyrenees. This part starts near the Basque Mountains by the Bay of Biscay. In this section, the average elevation increases as you move from west to east. The second section is the Central Pyrenees. This area extends from the Somport pass to the Aran Valley. It contains the highest summits, such as Aneto, Pico Posets, and Monte Perdido.

The third section is the Eastern Pyrenees. This area has a very uniform elevation. This uniformity ends at a sudden decline in a chain called the Albères.

Ancient stories offer different explanations for the name "Pyrenees." One Greek myth tells of a princess named Pyrene. In this legend, the hero Hercules caused her great distress. He later felt deep remorse for his actions. He cried her name so loudly that the mountains echoed his grief. This story suggests the mountains hold her name through the ages. Other classical sources suggest a different origin. They link the name to the Greek word for fire. The historian Diodorus Siculus recorded a story about herdsmen. He said a fire burned the mountains for many days. This continuous fire supposedly gave the range its name.

The landscape of the range is shaped by unique geological features. The mountains contain a high amount of granite. Granite is a type of rock that is very resistant to erosion. This helps the mountains maintain a massive and unworn character. One common feature is the cirque. A cirque is a semicircle of steep cliffs at the end of a valley. The Cirque de Gavarnie is a famous example.

This area also features the Gavarnie waterfall, which is 462 meters high. Another common feature is the gaves. These are mountain torrents that often form lofty waterfalls.

The range also contains many glacial lakes called ibóns.

Natural resources have been important to people in the Pyrenees for centuries. The mountains contain many marble quarries. The Romans opened many of these quarries in ancient times. They extracted prestigious marbles like Grand Antique. These stones were used to decorate famous sites like the Louvre in France and the Royal Palace in Madrid.

The range also has many mineral springs. Many of these are hot, sulfurous springs. You can find them in Andorra, Spain, and France. Additionally, the mountains contain coal and talc. The Trimoun open pit in France is a major source of talc in Europe.

The climate of the Pyrenees changes depending on where you are. The western part receives much more precipitation than the eastern part. This is because moist air blows in from the Atlantic Ocean. This air drops its moisture over the western and central sections. By the time the air reaches the east, it is much drier. The western and central Pyrenees also have some glaciers. However, the eastern Pyrenees do not have glaciers. Because there are few low passes, travelers often use tunnels. These tunnels run beneath major passes like Somport and Envalira to help people cross the mountains.
