Treasured Lands is innovative because it combines a coffee-table book with a guidebook, with both of them working in synergy. I hope that the book is more useful than a coffee-table book, and more inspiring than a guidebook.
However, the obvious objection is that it might be good for inspiration at home, but who wants to lug a beautiful 7+ lbs book on their travels? With that in mind, I've made available a PDF version of the notes, formatted especially for mobile, and available for a nominal fee for book owners.
This also solves the problem with the maps, which was the reason Laurent Martres chose to omit them. In print, we had to simplify them to keep it legible, therefore requiring the use of separate maps for real-life navigation. On the other hand, the electronic version supports zooming, so I was able to keep all the details present in the National Park Service maps, down to the trail level. It's like having all 59 official maps on your mobile device.
