The Great Salt Marsh is all that remains of Throxeus, once the greatest of all the oceans upon Barsoom.  The tides of Throxeus stretched across the entire northern hemisphere, and was a rich haven for all sorts of life. But as the oceans of the world dried up, Throxeus all but disappeared.  The remaining salt marshes now surround Gathol on all sides, helping protect the wealthy city from invaders.
