Michigan is one of the Upper Mid-West states and located in the Great Lakes region. It is bordered by Ontario, Canada to the north and Indiana and Ohio to the south. The borders with Illinois, Minnesota and Wisconsin are to the west, but are not land borders, but those of Lake Superior. The state capital of Michigan is Lansing, although the largest city is Detroit.
Michigan has a continental climate, but is in effect split in half, with the southern part being much warmer. The climate is of cold winters and hot summers, with the north having much shorter summers. Temperatures for the Grand Rapids area in January are 29f/16f (-2c/-9c) and in July are 82f/60f (28c/16c). Rainfall during the year is in the region of 36 inches.
With the lakes, there are a multitude of wreck dive sites. On Lake Superior there is the Bermuda, a 135 foot wooden schooner, with the top deck being just 12 feet below the surface. In the area, the most famous wreck is that of the Smith Moore, which was a steam barge and lies in 90 feet of water. Other wrecks are The Kiowa, The Manhattan and The Herman H. Hettler. The Steven M. Selvick was intentionally sunk some 16 years ago and is an easy dive for beginners. As these wrecks are all in the fresh water of the lake, they have remained very much intact and not degraded as they would in salt water.
At the Keweenaw Underwater Preserve the wreck of the Mesquite sits at 110 feet and was intentionally sunk after it ran aground some 25 years ago and was beyond repair, but is very accessible and a good dive.
