Pacaraima Mountains facts for kids
The Pacaraima Mountains are a long mountain range found mostly in Guyana, a country in South America. Parts of these mountains also stretch into northern Brazil and eastern Venezuela. These mountains are known for their unique flat-topped peaks and amazing waterfalls.

Exploring the Pacaraima Mountains
This mountain range stretches for over 800 kilometers (about 500 miles) from west to east. Mount Roraima stands as the tallest peak, reaching about 2,810 meters (9,219 feet) above sea level.
Mount Roraima is a special type of mountain called a tepui. Tepuis are like giant, flat-topped tables made of rock. They are often surrounded by steep cliffs that can be 300 meters (about 984 feet) high!
The Pacaraima Mountains are part of a much larger ancient landmass called the Guayana Shield. This area is also known as the Guayana Highlands, a region famous for its incredible nature. These mountains act like a natural wall, separating the Orinoco River valley in the north from the vast Amazon River basin in the south. They also help mark the borders between Brazil, Venezuela, and Guyana.
How the Pacaraima Mountains Were Formed
The Pacaraima Mountains are mainly a huge plateau made of sandstone. This sandstone formed from ancient layers of rock that were once at the bottom of a sea, long before dinosaurs roamed the Earth! Over millions of years, wind and rain have slowly worn away this sandstone. This process, called erosion, has created dramatic cliffs and the unique flat-topped mountains we call tepuis.
Besides Mount Roraima, other famous tepuis in this range include Mount Ayanganna and Mount Wokomung. Many rivers begin high up in these mountains. As they flow down, they often create spectacular waterfalls. One of the most beautiful is the Kaieteur Falls in Guyana, where water plunges a great distance! Important rivers like the Mazaruni River and Ireng River also start their journeys in the Pacaraima Mountains.
Amazing Plants and Animals of the Pacaraimas
Most of the Pacaraima Mountains are covered in thick forests. However, you can also find open grasslands, called savannas. These are especially common near the base of Mount Roraima and on the Brazilian side. These savannas are home to various grasses and scattered trees like the Curatella americana. Sometimes, these areas can experience fires, either naturally during dry seasons or started by people for farming.
It's hard to explore the steep slopes of these mountains. But scientists know that the isolated, flat tops of the tepuis are home to many unique plants and animals. These species are found nowhere else on Earth! This means the area has a "great potential for high species diversity." One common family of flowering plants found on these tepui plateaus is called Rapateaceae.
Protecting the Pacaraima Environment
Protecting this special environment is very important. Activities like cutting down trees (logging) and digging for minerals (mining) can harm the many different plants and animals that live here. To help protect this area, a large part of the range in Brazil is part of the Monte Roraima National Park. This park covers about 116,748 hectares (about 288,500 acres) and helps keep the natural beauty safe.
People of the Pacaraima Mountains
The Pacaraima Mountains have been the traditional home for indigenous groups like the Patamona people and the Macushi people for a very long time. The Macushi village of Tipuru is considered the oldest village in the South Pacaraima Mountains. It even has the oldest church and school in that region.
For these indigenous communities, the mountains and other landforms are very important. They are deeply connected to their stories and culture, passed down through generations. According to the Macushi people's beliefs, the mountains and other natural features were created by mythical brothers. These brothers cut down a special 'tree of life' called Wayaka. They also transformed people, animals, and other things into the rock formations we see today, giving these places a special, ancient meaning.
