Organ Pipe Cactus National Monument: Where Edges Meet (ISBN 187785669X)

Excellent overview of Organ Pipe and Sonoran Desert:
As a college Instructor for a desert ecology-adventure course, I highly recommend this book as a general overview of the Organ Pipe Cactus National Monument and the Sonoran Desert. Broyles eloquently covers all the main topics of interest in rich poetic detail, making the book both highly readable and informative. Ecology, or the interaction of biology and physical environment, is the principle theme of the book, with topics ranging from desert plant and animal life, human occupation by native Indians, ranchers and miners, the geology, weather, and seasonal changes, and even astronomy. And the pictures by Huey and overall design of the book are fantastic. A great book especially for newcomers to the desert because of its inspired intelligent overview of the multifarious yet holistically satisfying desert experience.

not for the traveler:
I bought this book because I was headed to OP Nat Monument and I wanted a reference guide. Unfortunately,it provided little in the way of useful information for someone visiting Organ Pipes National Monument. Not recommended.
