Bathymetric Map Great Lakes

Extremely accurate bathymetric map of the Great Lakes and surrounding area. Connected to the Atlantic Ocean through the Saint Lawrence Seaway and the Great Lakes Waterway, this collection of freshwater lakes represents the largest group on Earth and contains 21% of the world’s surface fresh water. Though the lakes reside in separate basins, they form a single, naturally-interconnected body of water. Of the five lakes, Lake Michigan is the only one that is located entirely within the United States; the others form a water border between the US and Canada. Over the past century, the lakes’ water level has only varied by about 6 feet. Niagara Falls connects Lake Erie to Lake Ontario.

This three dimensional map is carved from Baltic birch wood, framed and has a acrylic covering to protect the wood. Professional cartographers are used in the creation of each individual chart in order to insure the utmost accuracy. Some maps come in two sizes in order to fit virtually any area in the home, office or boat. We have charts from areas across the U.S. available on a drop ship basis. This is a great item at an unbelievable price. If you are searching for a particular area, please call or email.

The color will differ slightly with both the frame and background as each of the maps are hand stained and may vary from the picture.
