An underground canal connects the city with the Rhone River Valley to the northwest. Just below the left center of the image, the Durance River enters the scene. The river traverses the image generally east to west exiting the scene in the bottom right just before emptying into the Rhone River. The Berre Lagoon is visible just to the right of the center of the image. One of the runways of the Marsielles Marignane Airport is discernible extending out into the lagoon. The mouth of the Rhone River is visible at the right center of the image.
