The 4th edition of the Fieldbook will be printed this fall, and may be ready later this year, or right after the first of the year.
It is full color, and has 34 chapters - about 600 pages or so. The retail price is expected to be $19.95.
One section of the Fieldbook will be devoted to Leave No Trace, including use of stoves and campfires, backcountry hygiene and waste disposal, and traveling and camping in special environments.
The "Appreciating Our Environment" section includes chapters on nature, geology, weather, plants, wildlife, and astronomy, similar to the third edition.
