50 Circuit Hikes: A Stride-By-Stride Guide To Northeastern Minnesota (repost)

This is a terrific book for people who love to hike in NE Minnesota but have done all the typical trails. Yes, he covers common, over-used trails like the Split Rock River loop on the Superior Hiking Trail or the Bass Lake Trail north of Ely. But the real strength of the book is in all the obscure trails he's found off in the boonies, like the Eighteen Lake Trail or nice loops in the state parks. The book title isn't quite clear about this, but all of the hikes are loops, so there's no need to arrange a shuttle or completely return along the same route.

The natural history information for each trail is well done and reflects a lot of thought about the terrain. It's probably more information than most hikers really wanted, but if you take the time the night before your hike to read it through, it will definitely enhance your experience.
