IDAHO GEOLOGY

Idaho has outstanding examples of almost every type of landform, scientifically significant feature, rock type and mineral deposit--all featured in this book. The oldest rocks are more than 2.5 billion years old and contain a record of many of the events that transpired during this vast period of geologic time. During the last 20,000 years, Idaho has experienced major earthquakes, catastrophic floods, huge glacial ice sheets and volcanic eruptions. Hundreds of photographs and illustrations are used throughout the book to interpret the diverse geologic features and landscapes of Idaho and the northwest. This second edition of IDAHO GEOLOGY is completely up-to-date and includes the most recently published geological research on the subject.
