Putting it in perspective part II. Why do those 3,000' cliffs between Pololu and Waipio look like they do? Because the whole top of the north tip of the island sheared off under it's own weight and fell below the water. If it hadn't it would have looked like this. North Kohala is fertile grazing land for cattle. If all this was above sea level I can only imagine, with the alluvial runoff shown, what incredibly rich soil this plain must have.
