Birket Ram is located north of Mas’ada in the Golan Heights (now Northeastern Israel; formerly Syria). Using two 18mm images I was able to make this panorama. Click on the photo for a larger image.
Birket Ram is not mentioned in the Bible, but there is some related historical information.
Azaria Alon devotes only a single paragraph to Birket Ram, or Ram Pool.
Birket Ram is a natural water formation which measures 600 x 900 meters [1,968 x 2,952 ft.], reaches a depth of 6 to 10 meters [20 to 30 ft.], and holds about 3 million cubic meters of water. The pool has the appearance of a crater and is at an elevation of 940 meters [3,083 ft.]. It contains sweet water fed by underground springs and rain. Geologists believe that the pool was formed by volcanic activity in which the peak of the mountain blew off leaving a crater. (Israel National Parks & Nature Reserves, 2008. p. 39).
Josephus states that Panium [Paneas or Banias = Caesarea Philippi] is thought to be the source of the Jordan River. He claims, however, the source is Phiale (Birket Ram).
509 Now Panium is thought to be the source of the Jordan, but in reality it is carried there after a hidden manner from the place called Phiale:
510 this place lies as you go up to Trachonitis, and is fifteen miles from Caesarea, and is not far out of the road on the right hand;
511 and indeed it has its name of Phiale [vial or bowl] very justly, from the roundness of its circumference, as being round like a wheel: its water continues always up to its edges, without either sinking or running over;
512 and as this origin of Jordan was formerly not known, it was discovered when Philip was tetrarch of Trachonitis [Luke 3:1];
513 for he had chaff thrown into Phiale, and it was found at Panium, where the ancients thought the source of the river was, where it had been therefore carried [by the waters]. (Jewish Wars 3:509-513)
In 1865 Edward Robinson questioned the claim of Josephus saying,
This story helps to confirm the identity of Phiala with Birket er-Râm; but the supply of such a fountain as that of Bâniâs would exhaust this lake in a single day. (Physical Geography of the Holy Land)
Contrary to Alon’s claim that the water of Birket Ram is sweet, Robinson and other older sources say that the water is stagnant and slimy. I got no closer than the photo shows and can not testify about the quality of the water.
