Erwin Raisz Mountains shows an example of how to do symbol-style mountains with other elements, including canyons. The use of scarp-type symbols makes a big difference, but they tend to work for only a few basic directions without needing a new symbol.
http://makingmaps.net/2008/04/03/map...forms-terrain/ shows how to do this sort of thing for many different types of landforms. Getting analogous symbols is where the talent comes in, though, and I definitely can't help on that front...

Great link, Waldronate, even if beyond my drawing skills. Thanks for showing it.
