Click the image for full resolution . Similar shaded relief image of the bathymetry of the fossil high south of the transform fault. The area of this figure is outlined by the western dashed box on Figure 1, and is 20 km square. The nearly horizontal corrugated surface is about 10 km square in the centre of the image. Both corrugated surfaces are terminated at the end furthest from the spreading axis by normal faults throwing down away from the axis.
Side scan sonar images identify corrugations.
