Wonderfully written and informative book containing information on 69 Natural Areas and 9 Scenic Rivers located in Eastern Pennsylvania. The author describes each area in detail with information on ownership, size/designation, features, geology, wildlife and history. I really enjoyed this book and plan to visit the natural areas I have yet to see and revisit those that I have previously beheld and encourage others who are nature enthusiasts to read this book and discover where to find some of the best sites to visit in Eastern Pennsylvania.
