You learn something every day and today is no exception. Today I learned the definition of bathymetry, the study of underwater depth and topography. Below the Boat is a website and a company that makes these beautiful bathymetric charts, as seen above.
The charts are laser-cut into sheets of Baltic birch with hand colored detail. They also have a ton of maps too, from the East Coast to the Midwest and to even the West Coast regions. I particularly like this map of Lake Michigan- a lake I have spent a good deal of my life on, in, and around.
