The Gilf Kebir plateau lies in the south-western corner of Egypt. 10,000 years ago the area was alive with people, animals, rivers, vegetation and oases. Zerzura, the Lost Oasis may lie somewhere in this area. Along the way to Gilf Kebir there are spectacular geological sites: the White Desert chalk formations and mud lions or yardangs are mounds formed by process of wind erosion. There are also spectacular prehistoric sites: at Wadi Soura, László Ede Almásy discovered several painted caves in 1933. The Mestikawi - Foggini Cave is a discovery in the Gilf Kebir plateau made in 2002. This newly found site offers hundreds of examples of prehistoric paintings. Al-Aqaba leads from the desert floor to the top of the Gilf. The petroglyphs at Wadi Hamra lie deep inside the Gilf and the Great Sand sea transforms itself continually. These photographs were made taken in winter of 2003 – 2004 during an ex-cursion.
