Great Lakes Diving Guide

This book has a ton of info on hundereds of dive sites in the great lakes! Primarily focuses on the fascinating wrecks that can be found in the lakes. Major sites have a small blurb about the history of the wreck and a small black/white picture or map/drawing. LORAN location and lats and lons. Suggested dive profiles.All sites have a depth and suggested experience level for the dive and a brief discription. Sites are grouped together by location and international borders are ignored - great for both US and Canadian divers! Some info about dive operators and accomodations to certain areas.Overall, an excellent resource! I'll never be able to dive all the interesting sites in one lifetime. Provides enough info to spark a desire to explore the site but doesn't give too much away.
