The one I'm trying to find is more like a Stephen King novel, if I remember correctly.
I first came across "Forest and Crag" in the Columbia-Greene Community College Library back in the 90's. I was hiking the Catskill and Adirondack mountains during that time with a large dog who required vigorous exercise. The book was a good resource for discovering new trails to explore. It was out-of-print for awhile and I bought a copy for myself a few years back when it was re-published in paperback. I've used it to look up information but never read the whole book.
I have since re-located to Western Mass and have a young dog who I'm breaking in on some local trails. When I can trust him off-leash, I plan on hiking some New England mountains, so I've started reading F & C cover to cover. I'm sure it will lead to seeking out books with more detail on specific regions.
Thanks for the tip on Katahdin. I just read the chapter about creating the Monument Line in F and C. I'd love to read more details on that story.
