The book is a humanistic look at the land, history, and people of Westchester. Chapter 3 deals with geological topics. Unfortunately, there are a number of errors in geological terminology and interpretation. As remarkably complete and beautifully illustrated college level text, it includes many recent developments and regional examples of geologic features. This is a relatively simple source book for the identification of rocks and minerals.
Several chapters mention the geologic history of the metropolitan region.
Dr. Thaler is a weather historian who has compiled statistical tables from about a dozen Westchester and Putnam County weather stations. The brief sections on geology, geography and prehistoric climates may be of special interest to the geologic enthusiast. This book features some information about the local region, but the Westchester area doesn't seem to be its strength. Coverage of upstate New York may make purchase worth while for the traveler. As a paperback guide that provides many insights into details of the landforms of the Hudson Highlands, it contains some excellent photographs.
