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.
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 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. Geologicallythe 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.
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.
