Had an older edition and bought the most current edition. Very well written.
Format: Paperback
Classic text. Written at the college level.
Text treats each topic initially from point of what are the causes of this injury, and how to prevent it. Then it goes into what will need to happen with an occurrence.
No pictures, but that's a good thing. There are many drawings which do a better job of highlighting what is important.

Great Reference
Format: Paperback
This is an excellent, concise book with easy-to-read excerpts and diagrams that we are keeping as a reference guide for our Search and Rescue Team, some of whom are Wilderness First Responders but sometimes need additional information.
