Lake Michigan is the second largest Great Lake by volume and the only one located entirely in the United States. The lake’s shoreline is more than 1600 mi/2575 km and the average depth is 195 ft/59.4 m. Lake Michigan and Lake Huron have the same surface elevation and are technically a single lake. They are actually connected by the Straits of Mackinac, where many ships have foundered due to heavy storms. The Straits of Mackinac Underwater Preserve, located at the northern edge of Lakes Michigan and Huron, tries to preserve Michigan’s shipwrecks for next generations. One of the shipwrecks found is Colonel Ellsworth.

Scuba Diving in Mac’s Ground, Adelaide, South Australia Australia
The metropolitan area of Adelaide is famous for the variety and great number of diving sites it has to offer (you can visit here some of the most impressive shipwrecks in the whole world). The waters have the perfect temperature for scuba diving (warm during the summer and crystal clear during the winter), and are generally friendly and uncrowded.
Mac’s Ground, a popular site for divers of all levels, is a 150 m/492 ft long reef system with a small cave. Marine life in the site is spectacular. Be prepared to see cuttlefish, squids, old wives, strongies, Blue Devils, spider crabs, bullseyes and many more. There are practically no hazards in the area as the currents are pretty low.
