Though done in the late 1970's, this guide is still accurate in many cases and at the very least will tell you where the historic trails were, if they are not there now. The explanations are the best you can get by a long-time outdoors editor for the Arizona Daily Star who knows just about everything about every trail in the Tucson area.
