Egypt's Western Desert is full of
wondrous natural phenomenon and surprises. Sometimes one wanders
over a ridge or through a pass and discovers alien worlds, such as
in the White Desert. Less known perhaps, but growing in popularity
is the ancient plateau known as Gilf Kebir (Great Barrier), its
sides now heavily eroded and penetrated by huge sand wadis and
incredible dune systems which, at one point, rise 300 meters to meet
the level of the plateau, an irresistible force meeting an immovable
object! Amid this most awesome of natural settings, is located
unquestionably one of the richest storehouses of prehistoric rock
art in the world. The Cave of the Swimmers is the most famous, but
recent discoveries have
revealed
many other incredible sites dating back more than 7000 years, and
there is certainly much more to be explored.
New discoveries continue to be
made, with arguably the single finest rock art site in the Sahara,
the Foggini-Mestekawi Cave, being discovered only in 2002. It is now
thought that the original inhabitants who created these stunning
images influenced early Pharaonic cultures, and trade items have
been discovered that demonstrate the links shared by these early
peoples. In certain locations one can still find Mesolithic
arrowheads littering the sands, huge natural amphitheatres and, some
claim, the lost oasis of Zerzura.
In
recent years, Gilf Kebir has become a fairly popular Egyptian
tourist destination for the more adventurous travelers, not just for
the rock art and perhaps a chance to make an amateur discovery, but
also for the sheer grandness of the landscape. It also shows how
varied are the Egyptian antiquity sites.
The Gilf Kebir is a flat-topped
limestone plateau located about 150 kilometers north of Gevel
Uwaynat, covering over 7,770 square kilometers. It is situated in
the southwestern corner of Egypt about 720 kilometers from the Nile
and 960 kilometers from the Mediterranean. Like a huge shelf the
size of Switzerland, it is nearly dissected in two by a large cap.
It rises 300 meters from the
desert floor (1075 meters above sea level), forming one of the most
formidable barriers in Africa. Dozens of wadis extend into the
desert around its perimeter. these wadis were formed by water
erosion in a wetter phase thousands of years ago in the late
Tertiary age. Then it was a great divide, draining water in all
directions, north, south, east and west.
The
cliffs in the south and the southwest are the highest. The cliffs in
the northeast have been broken down into small islands of land. Wind
and water have combined to work away at the Gilf Kebir for over
100,000 years. Although it probably took its present form in the
late Tertiary, or early Quaternary time, the only reason it is still
standing is its tough cap of solidified sandstone.
The northern portion of the Gilf
Kebir is drowning in sand from the Great Sand Sea. It is helping the
wind break down the Gilf into small islands and cones. That sand is
whitish. The sand at the middle of the plateau is reddish. Wadi
Hamra, as its name states, if filled with red sand. The southern
portion of the Gilf is 5.800 square kilometers. The sand on the
western
half of the southern portion
is also red, as are the dunes to the northeast of the Gilf.
Around 9500 BC, the monsoonal
system shifted northward and lakes formed around the Gilf. Then, by
4500 BC the conditions were once again arid.
Penderel, in a paper presented to
the Royal Geographical Society in June of 1934, says that John Ball
was the first westerner to see the Gilf, while on patrol in 1917.
However, credit for the discovery is given to Prince Kamal al-Din,
who actually reached it, skirted its southern cliffs, fixed it on
the maps and named in in 1926.
In 1932, an expedition was mounted
to explore the Gilf by air. It included Sir Robert
Clayton-East-Clayton, Count Laszlo Almasy, P. A. Clayton and
Penderel.
As a bit of trivia, one may note
that the fictional story, the "English Patient", was based on the
life of Almasy. He came from an untitled Hungarian family, but
claimed to have driven the car of the last Hapsburg king, Karl IV.
In return, the king made him a count.
They
discovered several valleys rich with vegetation, including what
would later be known as Wadi Hamra, Wadi Talh and the Wadi Abd
al-Malik. These valleys were used by tribesmen for grazing and some
explorers believed that they were the lost oasis of Zerzura.
Archaeological work was begun in
1933 by Fronbenius, focusing on rock art. Prehistory work began with
Bagnold's expedition of 1938, done by O. H. Myers and H. A. Winkler.
This expedition was a joint effort of the Egypt Exploration Society,
which supported Myers, Gray and Winkler, and the Royal Geographical
Society, which provided grant money to Bagnold. During World War II
the Italians had a base in the region, while the British set up at
Uwaynat. The Long Range Desert Group of the British Army were active
in the area.
The
Bagnold-Mond 1938 expedition spent a month working around the Gilf
Kebir. They did a huge amount of survey work, archaeology and
geophysical and geological investigation. An additional month was
spent at Uwaynat where Hans Winkler joined them. While Winkler was
at Uwaynat, Bagnold and Peeol went north along the western side of
the Gilf and found two more rock art sites, one of which was a
totally new discovery.
Recent exploration began with
Misonne, the Belgian who crossed 600 kilometers of the high plateau
in 1969. He found that sheep, foxes and lizards lived on top of the
Gilf. Issawi in 1971 and 1972 did a geological survey, followed by
Wendorf in 1974 and al-Baz in 1978.
Between
1976 and 1977, the Deutsche Forschungsgemeinschaft and the Academy
of Sciences of Egypt launched an ongoing geological program under
the leadership of Lkitzch and supported by the Continental Oil
Company (CONOCO).
In 1978, a new type of explorer
came to the Gilf Kebir and Gebel Uwaynat, looking for answers to
questions that were from out of this world. The two week expedition
of seven Americans and nine Egyptians led by Farouk al-Baz was to
"verify in the field interpretations of tonal variations and
surface patterns observed on Earth-orbital photographs." They wanted
to compare the Libyan Desert, particularly around the Gilf and
Uwaynat, to photos they had of Mars.
The Northern Side of the Gilf
Kebir can be a bit disappointing to some, as it has broken down
considerably over the years and one does not have the sense of
approaching a huge plateau with many high cliffs and wadis as one
does on the southern and western sides. However, there is a
spectacular event taking place here. The southern edges of the Great
Sand Sea have now reached the Gilf Kebir, and one can observe two
great natural forces at war with each other.
In two huge valleys
before Lama Point they clash in an incredible phenomenon. The sand
is filling up these wadis. The individual dunes climb over each
other on the far side of the wadi, forming a moving ladder that
eventually reaches the top in the far left corner. Here the sand
spills onto Lama Point. There must be trillions of tons of sand
banked up against the far wadi wall, climbing up and over and up and
over, fighting its way to the top.
Lima Point sits at the southwestern side of
the first valley. After it, at Almasy Mountain comes the second dune
filled valley. Here, too, the dunes are climbing. They look like
they are eating the Gilf and they have reached the top of it here as
well. During the coming decades we shall see if they succeed in
breaking down the Gilf. What happens once they all reach the top is
anyone's guess.
The
plateau of the Gilf Kebir itself is gravelly and mostly featureless,
with big slabs of basalt in some places and at least one old
riverbed. The edges of the plateau are another matter. Like a
voyeur, one peers into amazing worlds filled with exotic scenes.
As one travels north-northwest along the
western edge of the scarp, valley after valley can be seen from the
top. Where the northeastern scarp has few true cliffs, just eroded
hills and dune filled valleys, the northwestern side is all cliffs
and spectacular views onto the Libyan plain below. Along here, there
is a Black Valley, a Red Sand Dune Valley and a valley where one can
walk down to the desert floor. All of these are to the south of one
of the most famous valleys called the Wadi Sura, the Picture Valley
of Almasy.
At the extreme northern section o the Gilf
Kebir stand the entrances of three wadis known as Wadi Hamra on the
northeast, Wadi Abd al-Malik in the center and Wadi Talh on the
northwest. These are the tree valleys that Almasy claimed were the
lost oasis of Zerzura.
After the explorers saw the valleys from
the air, they felt compelled to visit them on the ground. In 1933,
Almasy, Dr. Dadar, a geographer and geologist from Budapest,
Mr.
Casparius, a photographer and cinephotographer, Dr. Bermann and
Penderel journeyed to the Gilf once again.
Leaving Kharga on March 22, 1933, they
headed to Abu Ballas, visited Regenfeld and headed for the east side
of the Gilf. They climbed to the top of the Gif and found a camel
route to the plain below. Almasy went looking for another wadi, the
third, to round out Wilkinson's claim that Zerzula had three
valleys. What they discovered was that the Gilf has two parts, a
northern one and a southern half with a gap between them that Almasy
named al-Aqaba.
Upon reaching the end of the Wadi Hamra,
they climbed to the top of the Gilf. They found it flat, gravelly
and absolutely silent. There was no wind. They continued their
journey from east to west across the top of the Gilf. By the third
day they were close to the southern end, and by the fourth day they
found their way down and began moving north along the eastern side.
We do not know exactly where they descended, but there they found
another (unnamed) wadi and followed it for an easy ascent to the top
of the Gilf once more. In one of several caves in the wadi they
found rock art. The cave was large and the drawing were on the roof
and consisted of longhorn cattle, men and a cave or hut with bales
and bundles hanging from the roof.
In 1933, on the next trip into the desert
by car, Almasy talked with an old Tebu called Ibrahim Abd al-Malik,
a caravan guide from Kufra who had been one of the Kufra refugees.
It
was Ibrahim who called the wadi Abd al-Malik, Servant of the King.
He also spoke of Wadi Talh, the Valley
of Acacia.
They entered the Wadi Abd al-Malik on May
3rd. It is a long valley with lots of acacia trees. There were sites
of Tebu camps with grass huts and baskets. On May 5th, Almasy found
a second wadi, perhaps the Wadi Talh. Then the group left for
Uwaynat, where they met up with Ibrahim again. Now, the old Tebu
gave up the final bit of information. There was a third valley in
the group and it was called Wadi Hamra, the Red Valley (It had
already been found by P. A. Clayton). Here were the three wadis of
Zerzura mentioned by Wilkinson in 1830.
At the lecture given by Bermann at the
Royal Geographical Society, one more piece of the puzzle was finally
revealed, "As to the name 'Zerzura', our Tebu friend Ibrahim, asked
where Zerzura lay, said, 'Oh, those silly Arab people, they do not
know anything; they call these three wadis in the Gif, Zerzura, but
we local people know their real names.'"
