Libyan Desert
South of the coastal highlands of Cyrenaica is a large east-west running depression, extending eastward from the Gulf of Sidra into Egypt. This region of the Sahara is known as the Libyan Desert, and includes the Great Sand Sea and the Calanshio Sand Sea. The Libyan Desert is home to a few oases, including Awjila (ancient Augila) and Jaghbub.
