Based on the comprehensive, award-winning book Rivers of North America, the new Field Guide to Rivers of North America describes 200 of North America's most significant rivers in a reader-friendly, concise format. The guide is organized by geographic regions - each section begins with a map showing the relationship of rivers within one territory and a summary of the region's most important elements. Each individual river summary includes a two-page spread with a basin map, a full-color photograph and key river characteristics. The compact format of this guide will be particularly useful to scientists carrying out field research in areas such as field ecology, entomology, botany. It is an easy-to-use reference that can easily be packed away with other scientific gear. Anglers and recreational boating enthusiasts will find a wealth of information on river topography, native and nonnative fish species, as well as average temperatures that will help them plan their next adventure.
