This is a beautifully detailed, laser engraved and precision cut topographical map of the Long Island Sound in New York with the following interesting stats carved into it:
- Long Island Sound
- Long Island Sound is an estuary of the Atlantic Ocean, located in the United States between Connecticut to the north and Long Island, New York to the south. The mouth of the Connecticut River at Old Saybrook, Connecticut empties into the sound.
Interesting factoid: About 18,000 years ago, Connecticut, Long Island Sound, and much of Long Island were covered by a thick sheet of ice, part of the Late Wisconsin Glacier. About 3,300 feet thick in its interior and about 1,300 to 1,600 feet thick along its southern edge, it was the most recent of a series of glaciations that covered the area during the past 10 million years. Sea level at that time was about 330 feet lower than today. The continental ice sheet scraped off an average of 65 feet of surface material from the New England landscape, then deposited the material (known as drift) from the Connecticut coast into the Sound, creating what is now Long Island (the terminal moraine). (Not all of this information made it onto the map, we just love to read up on the lakes we design).
