That is not, however, the way many geomorphologists have seen it in recent years, particularly when using computers to model landscape changes, explained geologist David Montgomery of the University of Washington. "The funny thing is," agreed Korup, "a lot of these sophisticated models know a lot about the physics of erosion, but not rock types." His New Zealand study suggests that's a big omission. In fact, it turns the erosion-based approach to interpreting landscapes almost on its head. "You might be able to look at a mountain range and explain the slopes by the different rock types," said Montgomery. Korup hopes that someone will look at another fairly homogeneous mountain belt somewhere else to see how well this idea holds up. The Olympic Range in Washington, he suggested, might be a good candidate. Related Links: |
