Carved Lake Art is a company that creates laser-cut maps and depth charts of lakes and ports around the world, with an emphasis on the waters of the United States. They're cut from up to 8 sheets of Baltic Birch plywood and take the form of framed display maps, tables, clocks, and cribbage boards.
The company is based on the shore of Lake Michigan, so it's natural that the work began with the Great Lakes. But it has also produced nautical charts of New York City, San Francisco, the Mediterranean Sea, and more.
