Somebody a while ago in the banff subreddit found this image on Sunshine's facebook a while ago. Thought this was super interesting but unfortunately the text in the image is barely legible so the names of the routes are unknown. I doubt anybody would have a higher quality image but it would be super cool if one came up.
