If you consider Auerbach's Wilderness Medicine text to be "The Bible of Outdoor Medicine," then this will be a welcomed addition to your reference library. The fieldguide takes many of the most important topics from the original text(such as high altitude emergencies, envenomations, and trauma management) and paraphrases them just enough to be of benefit to both the weekend outdoor warrior and the expedition medic. I particularly was interested in the various ways to utilize common outdoor gear and improvise traction devices for orthopedic injuries. This book is also great in that it is small enough to fit comfortably in your backpack or glove compartment, readily accessable when needed. I highly recommend adding this book to your home or office library.
