The blue sea level is set at 880m asl, and clearly delineates the flatness of the Consuelo Tableland. Carnarvon Gorge is the embayment at the left of the image, containing a violet finger at 510m asl. The circle indicates a knickpoint1 transition between two surfaces. The lower profile belongs to the red line drawn along Clematis Ridge. It is about 17 km long, and shows at least 5 water gaps along the way. The gap furthest to the left is the entrance to the gorge.
