(10th edition, 2019). This guide, known by many as simply the 4-States book, includes many of the iconic hikes found in our beautiful mid-Atlantic region. Two things that make this edition so special are that all of the inside photos, 27 of them by editors Larry Broadwell and William Needham, are in color, and it has a stunning cover photo reflecting fall in Hazel Country by Barbara Southworth, used with her permission. As in prior editions, the guide features 25 circuit routes in the four-state area complete with trailhead GPS coordinates using the NAD83 system, and a detailed topographic map by Dave Pierce for each route. Three of the entries are entirely new. Others have been revised to vary routes described in prior years. Still others have been updated to reflect reroutes, historical research, and more. While some of the circuits are less familiar than others, all comprise a dayhiker's dream book.  132 pages  Measures 7" H x 4" W so it is small enough to put in your backpack.
