Roraima: Always On Cloud Nine

Dramatic clouds, heavy rains, and misty fog combine to create a climatic environment unlike anywhere else on Earth. Adiabatic cooling on Mount Roraima causes the formation of cirrostratus clouds and frequent rain. As moist air rises and multiplies, it cools and allows for the production of these specific clouds. The adiabatic process claims sole responsibility for the extraordinary cloud formations and numerous rain showers. Roraima's moist air rises, swells, and cools as it reaches the dew point. The ground gives birth to an eerie radiation fog when the rain ceases to fall.

Roraima has an equatorial and tropical climate type. Average temperatures are 24 degrees Celsius to 26 degrees Celsius. On the summit, temperatures can drop as low as 4 or 5 degrees Celsius. On account of the large amount of moisture existing in the air, humidity levels can reach a staggering 90%. Humidity, rain, and fog cause a physical struggle for the hiker. Proper gear is paramount if you desire to climb this mountain.

An Angelic Experience

Mount Roraima unveils an environment that encompasses cryptic caves and a breathtaking waterfall. Weathering produced the breaking down of rock formations and as a result, created massive boulders. Weathering also caused the bathing pools to form in the breakdown of rocks. The caves of Mount Roraima are two billion years old. Due to weathering, elongated, carrot shaped formations evolved.

Standing at 3,212 feet, Angel Falls takes the prize for the highest waterfall in the world. This waterfall is also properly named, as it exudes resplendence. The Caroni River in southeastern Venezuela actually starts its water flow from Roraima's slopes. An effluent stream leading to the waterfall carries the flow of water over the slope. This overland flow continues into another stream on the ground. Due to the high volume of sedimentary rocks, the groundwater is exceptionally porous. On Mount Roraima, the streams and Angel Falls work in perfect harmony to develop a hydrologic cycle. Explorers and scientists flock to view the incomparable grandeur of Angel Falls.  The Venezuelan park service strongly suggests hiring the indigenous Pemon Indians as guides, for this is their only source of income.

Roraima: A Real-Life Hidden Gem

Steep cliffs, a wide plateau, towering chasms, crystal pools, and small caves categorize the raw beauty that is Mount Roraima. Mount Roraima is the tallest mountain in Venezuela at 9,200 feet and there have been a few reports from climbers that have experienced light-headedness. At times, the trek can get quite arduous due to the steep cliffs, so the climb requires the climber to have a certain level of endurance. And you definitely don't want to forget the bug repellant! The sandstone rock began as sediment over 1.6 billion years ago. Mount Roraima is an extremely high, remote plateau. Quartzite has contributed to the formation of the plateau. Thousands of eroded quartz crystals are scattered throughout the bedrock. This metamorphic non-foliated rock is usually a light pink hue. Part of the plateau rim contains towering chasms. These chasms have deep cracks caused by years of erosion. The layer on top of the mesa is more resistant than the soft underneath layers.  Under the plateau, there is a jungle drenched in thick foliage with angular slopes. Above the jungle are rugged, steep cliffs. Blackened rock formations are enncased on the cliffs. These formations were caused by the remains of billion year old layers of eroded sediments from the Precambrian era. As a result of this accumulation of sediment, the mesa has come to resemble the qualities of a sedimentary rock. Embedded in these cliffs are several strands of colored materials called strata. Roraima has many diverse geographical elements that are both pleasing to the eye and help make the mountain even more unique. It is easy to see that Roraima has so much more to offer than just a strenuous climb.

My name is Sloane Solomon. I chose Mount Roraima, which is a mountain in Venezuela. It is eternally encased in billowy mounds of clouds, giving it an otherwordly appearance. I chose Mount Roraima, because I have always been fascinated with mountains. I love to read about their early beginnings on Earth and the enormous risks people often take climbing them. I have not been to Mount Roraima...yet. Although, I imagine it would be a once in a lifetime experience. Join me on this exciting adventure as we discover all the uniqueness and splendour Mount Roraima has to offer!
