I have an Earth-like world (approximately 1000CE technology--horse/mule for travel) that I want to have my characters traverse over the course of the book. I want the areas to have distinct geography/climate but, given the travel restraints, I don't want them to spend many many months on the road to get from place to place.
What I've gathered: Going from ocean to desert is simple, as is ocean to plains. But one of the key portions is getting from a tree-line mountainside, to a snowy and tree-rich place, down to a hot-arid desert and back to a coastal plain.
To be more specific, for those familiar with the climate terminology of the Koppen classification: I want to get between Dsa, Bwh, Bwk, Dfc, and Dfb all in one book.
I have been scouring the map for ideas of examples of this and the closest I can come to is the area surrounding and in Turkey, so if you have better Google-foo than I, please speak up with links and ideas.
