I thought about that, but erosion should generally "round off" things, rather than sharpen them. If you look at many mountain ranges, they look like heavily crinkled paper, with flat sections and sharp corners. It's like I wadded up a piece of paper, and then tried to press it flat. What's that all about? At 03:37 PM 11/22/2008, Hilarie Orman wrote:

But there aren't any ridges on Mandelbrot's hills. Where did they go? What's wrong with the model?

No erosion.
