More recently, European explorers made forays into the desert in search of Zerzura but never succeeded in finding it. Notable twentieth-century explorers Ralph Bagnold of Britain, and the Hungarian László (Ladislaus) Almásy led an expedition to search for Zerzura from 1929-1930 using Ford Model A trucks. In 1932 the Almásy- Patrick Clayton expedition reconnaissance flights discovered two valleys in the Gilf Kebir.
