In this 1957 Natural History Handbook on Saguaro National Monument by Natt N. Dodge you will notice an older style, and some dated information - but it is interesting how many of the plants, animals and places are still familiar and relevant today.
This book is part of a series of Natural History Handbooks produced by the National Park Service and 1972 and 1985 versions are also available:
- Saguaro National Monument, Arizona - Natural History Series - 1972
- Saguaro Official National Park Handbook - 1985
