Google Ocean comes to the Great Lakes

I was wondering if Google would be adding their “ocean” features to other bodies of water, and it turns out they are!  You can now dive into the five Great Lakes just as you can with the oceans.

From the LatLong Blog:

Users will be able to explore features such as the canyons and shoals in eastern Lake Superior, the Lake Michigan mid-lake reef complex, and the old river channel, now underwater, that once connected Lakes Michigan and Huron at the Straits of Mackinac.

In addition, the NOAA Great Lakes Environmental Research Laboratory has created a narrated Google Earth tour which you can download here (KML) or view directly in your browser.
