Does anyone know of any very detailed maps of the Presis? For years I've relied on AMC, Wilderness, and USGS maps for hiking and backpacking. Digital maps can also be useful. However, being the map geek that I am, I love to follow along on maps with books, videos, etc. For example, I am currently reading Ty Gagne's latest book and I've encountered some landmarks, gullies, etc. with which I'm not familiar. Most times I can figure it out by doing a bit of internet research but I just wondered if there is an easier way. Thx!
