Dr. Glen Fritz has been involved in the study of the Exodus geography since about 2000. He holds a PhD in Environmental Geography from Texas State University-San Marcos.
During his study of historical maps of the region, he noticed that older maps grossly misrepresented the Gulf of Aqaba (on the eastern Sinai Peninsula), or omitted it entirely. Yet, it was this body of water that the Bible seemed to describe as Yam Suph, the sea of the Exodus. The Gulf of Aqaba was not correctly charted until the 18th century, due to its isolation, lack of harbors and fresh water, and hazardous sailing conditions.
The historical map deficiencies suggested that the geographers and theologians of those times were ignorant of the size and shape of this gulf, a point that is corroborated in the ancient Greek and Roman writings. Hence, when the first Exodus traditions arose more than 2000 years ago, the only logical options were an Exodus sea-crossing near Egypt, and a Mount Sinai in the Sinai Peninsula. Subsequently, the location of the Sea of the Exodus was lost for most of history due to persistence of this geographical ignorance.
Realizing that the location of Yam Suph was not only a historical mystery, but the chief clue for the route to Mount Sinai, Dr. Fritz pursued the topic for his 2006 doctoral dissertation, entitled The Lost Sea of the Exodus.
