Explicitly the idea isn't so much about mapping a journey, but mapping in profile view (side scroller type) opposed to the traditional map view (bird's eye).
I see now the thread for the journey challenge, but all of these maps are in map view.

A traverse map is most natural for a journey, but is not restricted to a journey, so I edited the title of this post. This challenge is intended to work a skill set of landscapes applied to mapping. I can't find any examples of this, but if it has been done can somebody provide the link?

Cheers,
