It is a sandy region, located in North Africa, extends from western Egypt and eastern Libya. 74% of its surface is covered by sand dunes. Oasis, caves, precious stones and dreamlike landscapes make up this extraordinary and little known place. The Egyptian Great sand sea is parallel to the Calanshio sand sea of Libya, with which it borders to the north. The dunes cover approximately 10% of the total area of the western Egyptian desert. This sea of sand was well known to the merchants traveling with caravans through the Sahara. Friedrich Gerhard Rohlfs was the first European to document the Great Sea of Sand. He began his Saharan expeditions in 1865, and named the vast expanse of Grobe Sandmeer dunes, but it was in 1924 with Ahmed Hassanein's maps that Europeans could appreciate the expanse of the sandy sea.
The area is famous for the presence of quicksand, which is the reason for its existence, because it consists of layers of quicksand over a layer of limestone and over a large amount of groundwater and this is the reason for this large movement and therefore this area has recently been determined to be prohibited to pass through it History Many cases of disappearances in this area are mentioned. However, a tourist movement has emerged in the region in terms of tourists to see the landscape of the region, as well as the practice of sand skiing.

There are many theories about the origins of the unique Great Sand Sea glass you can gear more about them and get the chance to see it when you travel from Cairo to Siwa Oasis. Some think that it is related to radiative melting, or ancient warfare. The glass was first discovered by stone-age Aterian peoples, who made tools from the glass, and later by Egyptians. A polished piece of glass was centered in an elaborate piece of jewelry found in King Tutankhamen’s tomb. Since these times, the glass remained untouched because of the harshness and inaccessibility of the region.
It has been estimated that the glass of these was formed around 26 million years ago. The scientists believe that the glass is the chemical result of a meteorite colliding with the nearly 100% silica composition of the sand.
