Guyana Langscape Over Time

This map shows the Essequibo River Drainage Basin and
the various rivers that flow through Guyana. exemplifying
Guyana's fluvial landscape. 

Being named the Land of Many Waters, Guyana’s landscape is very much Fluvial. Fluvial is a term used in to refer to the processes associated with rivers and steams including the deposits and landforms created by them. Guyana can be divided into five natural regions; a narrow and fertile marshy plain along the Atlantic coast (low coastal plain) where most of the population lives; a white sand belt more inland (hilly sand and clay region), containing most of Guyana's mineral deposits; the dense rainforests (Forested Highland Region) in the middle of the country; the grassy savannahs in the southern west; 
the larger interior highlands (interior savannah) consisting mostly of mountains that gradually rise to the Brazilian border. 

1,000 years from the towns and villages in Guyana will be run down and decaying if not destroyed by weathering and flooding. Every year the rains flood the savannah. In many areas it is possible to move about only by boat during this season.

The above image shows the Rupununi, the grassy savannahs in the
southern west hemisphere of Guyana. Rupununi is an area of dry
grasslands with sparse trees, termite mounds and wooded hills.

Guyana, having one of the largest unspoiled rainforests in South America, some parts of which are almost inaccessible by humans. Approximately eight thousand species of plants occur in Guyana, half of which are found nowhere else. With more than 80% of Guyana being covered by rain forests, ranging from dry evergreen and seasonal forests to montane and lowland evergreen rain forests. I suspect in 10,000 the rain forest that occupies Guyana will grow and spread across the area of Guyana and cover 100% of the land. As the years go by the Tepui tabletop mountains in Guyana will slowly start to grow in height due to upward faulting and frosty weather. Seeing as the Tepui mountains have grown from In 10,000 years the Tepui would grow over 10,000 ft in height. By this time the roads would be flooded and washed out do to the amount of rainfall in the area. Further more, 1,000,000 years from now the land we known as Guyana will be over taken by foliage, rainforest and grass land; unrecognizable in comparison to Guyana today. In 1,000,000 Mount Roraima, Pakaramia Mountains, Mount Ayanganna and the Kanuku Mountains will be covered in moss and rainforest.

the unspoiled Rainforest in central Guyana

Beyond the ever going changes of earths surfaces the Land of Many Water know as Guyana will be completely altered and unrecognizable 1,000, 10,000, and 1,00,00 years from now.

Guyana Weather and Climate

The above image shows an example of lenticular clouds which hover near mountains in saucer like formations.

The local climate is tropical and generally hot and humid, though moderated by northeast trade winds along the coast. There are two rainy seasons, the first from May to mid-August, the second from mid-November to mid-January. This is the only predictable feature of the weather.  It is hot all the year round - temperatures seldom rise above 33 degrees (Celsius) during the day, or fall below 25 degrees (Celsius) during the night.  The aforementioned are the shade temperatures so actual temperatures could be higher. Considering, there is also a steady north-easterly wind off the Atlantic takes the edge off the heat on the coast. The air mass classification in Guyana would be mT which stands for maritime tropical seeing as the climate is humid year round.

The image to the left is an example of valley fog which is a result of cold air draining down from surrounding mountains and seems to hovers in the valleys of the mountains.

Majestic Landscapes within Guyana

Guyana also nicknamed the Land of Many Waters features various mountainous borders, which add character to Guyana’s majestic landscape. Some of the mountainous features within the land include The Kanuku Mountains, Mount Ayanganna, Pakaraima Mountains, and  Mount Roraima.

The Pakaraima Mountains were developed through processes such as: erosion, and weathering. Weathering is any of the chemical or mechanical processes by which rocks exposed to weather, undergo chemical decomposition and mechanical disintegration. Erosion on the other hand is the gradual wearing away of land surface material such as: rock, sediments and soil, by the movement of water, wind or a glacier, or the simple transport of weathered material.

Above is an image of Mount Ayanganna, a sand stone tepui in the Pakaraima Mountains. Tepui's “House of the Gods” are tabletop mesas derived from a large sandstone plateau that have been weathered and eroded.

The photo above is a great example of joints created by weathering. Joints are regularly spaced cracks or fractures in rock. In this particular photo the joints are the free spaces best seen right above the fractured edge of green or moss, depicted as small spaces that travel vertically up the mountain. 

Another example of weathering would be Frost Weathering. Frost Weathering is a mechanical process that occurs upon freezing. When there is an increase in the volume of the water, the water freezes, expands and exerts a force on its surroundings, the hydraulic pressure exerted by water deep inside the crack the water freezes at the top to create a seal. This can be exemplified in the photo on the left. Which is a photo of Mount Roraima. Frost weathering fractures can be seen at the top of the mountain as well as along the far right side of the mountain wear the rock is broken, creating a jagged stair case.

The Blue Mountains of Savannah: Faulting and Folding

The Kanuku Mountains also nicknamed “The Blue Mountains of Savannah.” The Kanuku Mountains are approximately 5000 km2 in area, located in the heart of the Rupununi Savannahs of south-western Guyana.  The Kanuku Mountains are said to be the most ecologically diverse area in Guyana. Geologically the mountains are marked with what is called normal and reverse faulting. As Exemplified in the picture below.

Faulting arise when underground pressure forces, pulls apart, or compresses tectonic plates, to further creating stress. Within the event of a fault rocks tend to be weak and break. Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas that undergo compression. Even though the mountain in disguised by Rain Forest there are many triangular facets along the sides of the mountains. Lining the base of the mountain valleys also form as a process of faulting.

Within the Kanuku Mountains there is also evidence of folding. Geological folding is defined as the varied striations and waves in rock or sediment. The Kanuku Mountains show aspects of overturned folding which is a result of dominate compression from one direction.

Introduction

Blog Created By Kelci Waller

            My name is Kelci Waller. I'm a Junior undergraduate student, perusing a bachelors in Business Management at the University Of Colorado at Denver. I have decided to dedicate this blog to Guyana also called the Land of Many Waters.  

Being a travel enthusiast and wanting to see the world and all its glory, Guyana has always been one of the top places to visit. Opposite of previous assumptions, there is a great amount of geographical features within Guyana including: the coastal plain, the white sand belt, the Amazon Rainforest and the interior highlands. Being that Guyana is not well known it drew me in to be a great topic of interest, allowing insight on all it has to offer geographically.
