Amazonia Rivers -Expeditions Manu Reserve
Amazonia Rivers -Expeditions Manu Reserve Alto Madre de Dios Manu River -Wildlife Observation Amazon Peru is a region in Peru, located in the Madre
de Dios Department, which is part of the Amazon Basin. The description you provided seems to be referring to a
geological feature along the Madre de Dios River.

The river’s open walls show three distinct layers: Amazonia Rivers -Expeditions Manu Reserve
- Lowest Layer: The reddish-colored earth at the bottom represents the old sea bottom. This layer dates back millions of years when the Amazon Basin was once an inner sea. Over geological time, the sea retreated, leaving behind sediment that formed the present-day land.
- Middle Layer: Above the old sea bottom, there is a layer of big stones, indicating ancient river bottom. These stones were deposited over time as the river eroded and reshaped its course.
- Top Layer: The top layer consists of the actual earth layer, which represents the current landscape and soil formation in the region.
This geological sequence provides valuable insights into the region’s geological history, showcasing the changes that have occurred over millions of years, shaping the landscape we see
today. Such formations are not uncommon in river valleys and can provide valuable information to geologists and
researchers studying the area’s past environments and geological processes .
The Alto Madre de Dios River is born in the Cusco region,
Peru, in the area of the Andes mountain range. Its source is in the region’s mountainous altitudes, and as it flows
east, it passes through different landscapes and ecosystems in the Amazon rainforest.
The Alto Madre de Dios River runs for several kilometers and then joins another important river called the
Manu River, which also originates in the Cusco region. Together, these rivers form the Madre de Dios River.
The Madre de Dios River continues its course northward, through the Madre de Dios region, and finally empties into
the Beni River, a major tributary of the Madeira River. The Madeira River is one of the main tributaries of the
Amazon River, so ultimately the waters of the Alto Madre de Dios end up as part of the vast Amazon River Basin in South America .
The Alto Madre de Dios River
is fed by several tributaries that flow from the nearby mountains and jungles. Some of the most important tributaries of the Alto Madre de Dios River are:
Manu River: It is one of the most significant tributaries of the Alto Madre de Dios River. The Manu River rises in
the Cusco region, like the Alto Madre de Dios, and joins it further down its course.
Tambopata River: Another major tributary of the Alto Madre de Dios River is the Tambopata River, which also
originates in the Cusco region and flows north to join the Madre de Dios River.
Las Piedras River: The Las Piedras River is another significant tributary that joins the Alto Madre de Dios River on its northward course.
These tributaries contribute their waters to the Alto Madre de Dios River, feeding it and increasing its flow as it flows
towards its mouth in the Madre de Dios River and, finally, in the Beni River and Madeira River, which are part of the
basin. of the Amazon river .
The Alto Madre de Dios- like other areas of the Amazonia Rivers -Expeditions Manu Reserve
is a region rich in biodiversity and is home to a wide variety of flora and fauna species. Next, I will mention some of the species that inhabit this region:
Flora:
Emblematic trees of the Amazon jungle, such as rubber, chestnut and cedar.
Medicinal plants used by local communities, such as cat’s claw, sangre de grado and ayahuasca.
Various species of palms, such as the aguaje palm, which is important for food and local crafts.
Fauna:
Mammals: The Alto Madre de Dios is home to a wide variety of mammals, such as jaguars, pumas, tapirs, monkeys (such as howler monkeys, spider monkeys, and capuchin monkeys), pink dolphins, and giant otters, among others.
Birds: There are many species of birds in this region, including macaws, toucans, parrots, hummingbirds, harpy
eagles, among many others.
Reptiles: Crocodiles, alligators, boas, anacondas and various species of snakes are part of the reptilian fauna present in this area.
Amphibians: Frogs and toads, like the famous brightly colored poison dart frog, are also found in the Alto Madre de Dios.
Fish: The Madre de Dios River and its tributaries are home to numerous species of fish, some of which are important for subsistence and commercial fishing in the area.
Insects and Arthropods: A wide variety of insects and spiders, including vibrantly colored butterflies, beetles, ants, and many others, are part of the region’s rich diversity
