The depths indicated in the lower portion of the figure are characteristic of this profile only, as the depths of all provinces gradually fluctuate along the length of the ocean basin.

On these profiles of the western North Atlantic the step provinces are shown as a series of tilted fault blocks bounded by scarps. The difficulty of tracing the steps from one profile to another is apparent. {\'ertical exaggeration 40:1.).
