I am lucky to live within a few minutes’ drive of the east side of Georgian Bay (Lake Huron), which means I have access to some of the best fresh-water wreck diving in the world. Perhaps less mysterious, and more directly human of course, but also a delight and wonder. For the vast majority of wrecks, the pages are often blank before the mid-19th century. That’s a total blast, if somewhat impersonal. In a cave, that link to history covers tens of millions of years from the warm seas of the Cretaceous to the bones of Paleolithic megafauna. Defining their attraction isn’t an easy ask. It’s rather like trying to explain to someone what it is about a couple of friends that makes them friends. The appeal of each type of diving-seemingly poles apart-is difficult to put into a simple sentence. But when asked, “What’s your favourite dive?” in addition to a bunch of cave dives that float to the top of consciousness like cream on top of pail of fresh milk, there are some truly fantastic wreck dives. As a kid, caves fascinated me and since then it’s simply grown to become an obsession of sorts. Personally, I love cave diving more than anything else. What kind of dive turns your crank? Cold water wildlife, tropical reefs, shipwrecks, caves… what’s your poison? By Steve Lewis Take a stab at sorting out that jumble of wood and rope on your next wooden shipwreck dive
