Mark Lehner (born 1950 in Dakota[citation needed]) is an American archaeologist with more than 30 years of experience excavating in Egypt.
Intrigued by the mysteries of the "Sleeping Prophet", Edgar Cayce, Lehner "found that [my] initial notions about the ancient civilization along the Nile could not stand up to the bedrock reality of the Giza Plateau".
[1] He turned to the scientific method of discovery in order to understand the culture better, returning some years later to complete a doctoral degree at Yale University.
Lehner's team has more recently included parts of Menkaure's valley temple and the town attached to the monument of Queen Khentkawes in their excavations.
[5][6] Lehner took part in an American Association for the Advancement of Science debate centered around controversy surrounding the age of the Sphinx at Giza.
