Waw an Namus Physical Description

Despite not being its most notable feature, the sheer size of Waw an Namus quickly grabs the attention of visitors. That’s because the caldera itself measures a staggering 2.5 mi (4 km) in diameter. This same feature also boasts a depth measuring roughly 330 ft (100 m).

Nestled within the confines of the already remarkable caldera itself, though, lies an equally impressive scoria cone. This natural formation itself measures about 0.81 mi (1.3 km) wide at its base. This section of the volcano also has a height of approximately 460 ft (140 m).

Yet, amazingly, this feature holds yet another crater! This particular one, though, happens to measure roughly 260 ft (80 m) deep, and 490 ft (150 m) wide. The remains of yet another one is situated on the western section of the summit of the crater of Waw an Namus.

Its wonders do not end there, however. A darker colored layer of volcanic fragments extends outward around the central site. This layer, called tephra, extends a mind-boggling distance of 12.4 mi (20 km) in some directions. Its depth ranges from 0.8 – 59 in (2 – 150 cm).

Waw an Namus Location, History, and Ecosystem

The mesmerizing site known as Waw an Namus formed in a part of the world that may shock some individuals. That’s because it lies within the confines of the Sahara Desert! More specifically, it’s found in the Fezzan region of the country of Libya, in Africa.

To this day, the exact age of the structure remains a source of debate among researchers. Studies place its formation at somewhere around 200,000 years ago, give or take about 9,000 years. The scoria cone in the center, though, may be only a few thousand years old.

Incredibly, three small lakes actually lie within the caldera of Waw an Namus. Given that evaporation rates in the region exceed precipitation rates, that’s believed to be fed by groundwater. These have a total surface area of around 0.12 sq mi (0.3 sq km).

These lakes remain relatively shallow, however. In fact, the maximum depth of the deepest only reaches 49 – 52 ft (15 – 16 m). Seasonal variations affect the altitude of these bodies of water, as well. Nonetheless, this averages roughly 1,424 ft (434 m) above sea level.

Various other small bodies of water also appear within Waw an Namus. These, however, tend to come and go. All of them sometimes display various shades of red. Unsurprisingly, the colors derive from varying chemical compounds in the surrounding rock strata.

Eye of the Sahara Physical Description

The amazing Eye of the Sahara immediately captivates all those who learn of it. Obviously, its sheer appearance represents an intriguing sight for many individuals. But, the sheer physical dimensions of this natural marvel nevertheless equally astounds the informed.

The formation boasts a roughly circular shape, with slightly irregular outlines. Overall, it holds a diameter that measures a stunning 25 mi (40 km). It’s also composed of several concentric rings. The largest of these, the central area, is roughly 19 mi (30 km) in diameter.

Each of its rings manifests a wall, called a dike. The inner ring dike averages 65.6 ft (20 m) thick. It sits about 1.9 mi (3 km) from the approximate center. The outer ring wall, though, is larger, at roughly 164 ft (50 m) thick. But it lies about 4.3-5.0 mi (7-8 km) from the center.

A wide variety of rock structures also appear within the various sections of the Eye of the Shara. These include differing volcanic rocks, gabbros, carbonatites, and kimberlites. Many of these seem to have originated from ancient lava flows within the awesome structure.

Nature didn’t simply stop there, though, when creating this masterpiece. As if these weren’t enough, numerous hydrothermal features also exist inside he confines of the site. These include a multitude of formations consisting of sandstone, silica, and limestone.

Eye of the Sahara Location, Structure, and Mysterious Origins

The location where the mesmerizing Eye of the Sahara formed probably won’t surprise many people. That’s true since it lies in a region of the world already quite well known for its abundance of natural marvels. The site sits on what’s now the continent of Africa.

What’s more, its location’s also extremely remote. This aided in its eluding discovery until modern times. It’s to be found in the western section of the country of Mauritania. This, as the common name clearly indicates, places it in the equally fascinating Sahara Desert.

Situated in the northwestern section of that continent, it’s further located inside another remarkable place. That amazing feature itself remains known, especially locally, as the Adrar Plateau. In the country it appears in, this puts it in the western central portion. 

The Eye of the Sahara represents what scientists call an elliptical dome, albeit a highly eroded one. Several distinct layers of sedimentary rocks appear inside its walls. A wide variety of minerals are present, as well. These include limestone and quartz-rich sandstone.

It’s widely believed by the majority of geologists to be the result of uplift. Evidence indicates that its creation began approximately 100 million years ago. Studies undertaken in the 1950’s and 1960’s, in the minds of most researchers, disproved the impact theory.

Erg Chebbi Facts

Erg Chebbi Physical Description

The amazing feature known as Erg Chebbi amazes those who encounter it for a variety of reasons pertaining to its physical characteristics. It’s impossible to say which of these ranks as most impressive, though, because individuals perspectives naturally vary.

This product of natural forces represents a comparatively large example of what’s called a dune sea. It directly owes its formation to the action of widblown sands, accumulated over a vast span of time. Beneath them, however, lies a rocky base, known as a hamada.

Perhaps the most remarkable trait of this site, for the majority of individuals, is its sheer height. That’s due to the fact that these attain heights measuring as much as 492 ft (150 m) in some locations. These rise from the surrounding terrain, creating a visual masterpiece.

Yet the earth wasn’t content to simply stop its efforts here at pure size alone. Combined with the actions of local forces, random chance also created a highly unique shape here. More precisely, this wonder of the desert possesses a roughly rectangular shape.  

Erg Chebbi also displays other respectable dimensions. Running from north to south, this imposing structure measures about 31 mi (49.9 km). Extending east to west, however, it extends about 6.2 mi (10 km). Both of these vary, of course, due to local conditions.

Erg Chebbi Location and Ecology

The visual marvel known by the name of Erg Chebbi formed in a remote region of the globe. This area is already renowned for its abundance of natural wonders. That’s due to the fact that it’s situated on what now bears the moniker of the continent of Africa.

More exactly, it lies in the extreme northwestern portion of the continent. Its location further places it within the confines of the country of Morocco. The varying boundaries of the structure also coincidentally cause it to roughly line the border with Algeria.

As a general principle, the local climate of the surrounding area developed as quite harsh and arid. As remains typical of such regions, vegetation amid the stark beauty of the site also generally qualifies as almost non-existent within its boundaries.

Largely due to this situation fauna also remains extremely scarce within its boundaries. The few known species that do survive inside this dune field in sporadic concentrations include pink asphodels, mauve statice, Fennec Fox, desert hedgehog, and jerboa.

Researchers discovered an entirely new, and physically distinctive, species of wolf spider living within the confines of the erg. A preliminary scientific study of this new species remains underway. Therefore, no detailed information about it is available at this time.

The predominant weather patterns of Erg Chebbi classify as seasonal and generally quite unpredictable. Sandstorms also occur frequently and often arise with little warning. Rainfall within the boundaries of this remarkable site also occurs highly infrequently.
