Percé Rock

earth science Maturity 11-13 Next article →

Percé Rock is a huge stone formation in the sea. It sits in the Gulf of Saint Lawrence in Quebec, Canada. This massive rock looks like a ship under sail from far away. It is a famous icon of the Gaspé Peninsula. People call it many names, like Pierced Rock or Split Rock.

The rock is a natural arch made of limestone. This type of stone is very special to the area. It is a major place for people to visit in the Gaspésie region.

The rock changes because of the wind and the water. Over a long time, the waves cut through the stone. This creates large holes called arches.

Long ago, the rock had three arches. In 1534, Jacques Cartier saw three arches in the stone. Later, two of those arches disappeared. One large arch collapsed on June 17, 1845. Now, only one big arch remains. It is a high, gothic-style arch. A small boat can even pass through it when the tide is high.

History helps us understand how old this rock is. Scientists say the limestone is from the Devonian period. This was more than 400 million years ago.

In 1844, Sir William Edmond Logan mapped these rocks. He is known as the father of Canadian geology. In 1607, Samuel de Champlain named the rock Percé. This name means "pierced rock" in French. He chose this name because of the holes he saw in the stone.

There is so much life living around the rock. The rock is part of a national park founded in 1985.

This park is a safe place for many birds. Over 110,000 northern gannets nest on the nearby Bonaventure Island. You can also find puffins, razorbills, and kittiwakes there. In the water, people see blue whales and humpback whales. The rock also holds 150 different species of fossils. These fossils include ancient corals and marine worms.

Percé Rock is a giant part of the natural world. The whole mass is estimated to weigh 5 million tonnes.

Even though it is huge, it is slowly changing. The wind and water take away about 300 tonnes of rock every year. Because of this, scientists think it might disappear in 16,000 years. At low tide, a sandbar connects the rock to the land. This allows people to walk toward the rock on foot. It is a wonderful place to learn about the Earth.
