Filling out with potential ski tours. As with my other "Research" map (https://caltopo.com/m/SSACB), 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, checking conditions, etc. If you need more details, get the relevant book(s): - "Ski Tours in Southern California", Daniel E. Anderson (ISBN-13: 978-0961452742) - "Ski Touring in California", David Beck (https://archive.org/details/skitouringincali00beck) - "Ski Tours in the Sierra Nevada, Volume 1: Lake Tahoe", Marcus Libkind (ISBN-13: 978-0931255083) - "Ski Tours in the Sierra Nevada, Volume 3: Yosemite, Huntington and Shaver Lakes, Kings Canyon, Sequoia", Marcus Libkind (ISBN-13: 978-0931255021) (more as I add them)
