This book is from wilderness adventures press inc, belgrade montana. It doesn't tell you how to fish. It's all maps with detailed notes on each with all the info you need on what fish are there, regs, put in, take outs, public and private lands, access points, mileage , etc. It also shows where giant stoneflies come out of the water onto land looking for unsuspecting anglers, lol. Very useful for rafting, too.
