Filling out with potential ski tours; as with my other "Research" map, green is routes I've already done (but happy to do again), red is for ones I haven't done yet (but keep in mind I might have taken another route to the same objective). Where I reference books, I put all their routes in a folder with the format "Book Title" (Author's last name). This map is meant as a supplement and only for tracing out routes. If you need more details, get the relevant book(s).
