Wouldn't you know it...there are many caves in the area...
In Neogene, intensive orogenic movement accompanied by folding and faulting began, and the Rift Valley was repeatedly thrust down. Therefore, the Bekka Valley was filled with deposit from many small rivers which flowed from the rising Lebanon and Anti-Lebanon Mountains. On the other hand, transgression occurred in the Mediterranean coastal region in the Miocene and Pliocene, and limestone of 300 to 400 m in thickness was deposited, forming Karst plateau at Ras ech Chaqaa area near Tripoli. Towards the end of the Pliocene this area became approximately like its present topography. The most characteristic thing in the Pleistocene was the activity of volcanoes, and there was basalt flow at Jebel ed Drouz in Syria. In the above-mentioned vicinity of the border to Palestine, where the bottom of Rift Valley rises sharply, such a basalt flow is also seen.
As a result of the change in the sea level, typical marine terraces have developed along the Mediterranean coast of Lebanon and Syria. They can be roughly divided into 3 or 4 terraces which were studied by DE VAUMAS (1954), FLEISCH (1956, 1962), BUTZER (1958), H. E. WRIGHT (1962), etc., and are correlated with the marine terraces in southern Italy. However, opinions are still not unanimous. The group of caves containing prehistoric remains, which is closely related to our present research, is distributed near the coast. The caves are from north to south, Ras Lados, Abou Halka, caves near Enfe, Es Stouh, Asfurieh, Ras el Kelb, Adioun caves, etc. These cave sites are situated about 10 to 15 m above sea level, and from a topographical view-point, such caves or shelters were formed by the erosion of the sea during the period when the sea level was stable for a certain period. Therefore, by doing careful research on these prehistoric sites, there is the great possibility of determining their relationship with the marine terraces, in other word, their geological age.
And...the "Anti-Lebanon" Mountains? Guess they were hard-up for names....
