Mapping Mountains

I threw together a quick map of southeastern France to experiment with a different method for mapping mountains. I took data from http://www.peaklist.org/lists.html hoping that showing peaks as opposed to direct elevation might be more useful for gaming. I'm not really happy with the results: even if I cleaned it up, it wouldn't do what I really want, that is help you visualize the landforms better than traditional maps of both the earth and in gaming. I think I may stick to traditional hillshading. I am also thinking of experimenting with slope, which might be useful in a game; knowing how steep the landscape is that the PCs have to travel over, but I'm not optimistic about it.
