What is the erg? In Arabic, the word designated tracts of sand in North Africa, they are characterized by the presence of dunes and dunes, as well as the almost complete absence of vegetation. Grand Erg Oriental — a huge sand desert in the northern part of the Sahara with an area of over 100 square kilometers (more than 600 km length of the erg., Width in some places reaches 200 killometrov).
The bulk of the sands is situated on the territory of Algeria, but a small tip of the erg «climbs» in Tunisia. Dunes Great East Erg have light yellow color and long, sharp ridge line parallel to the direction of the prevailing wind. The height of some dunes up to 300 meters, is characterized by the separation of their clay-pebble walkways (Gussie).
Getting to the Grand Erg Oriental can either by car on a pretty good road, or on local airlines to fly to the airport of Hassi Messaoud oil, which is located directly inside the erg.
People who have visited the Sahara, said that the endless ergs sandy sea calms and purifies the soul. I, as a person still will not visit any of the Big ergs, it’s hard to judge the truth of these words, but I know one thing for sure — there is shortage of water during the day and 45 at night near zero.
