This is a beautifully detailed, laser engraved and precision cut topographical Map of Duck Lake in Highland Charter Township in Oakland County, Michigan with the following interesting stats carved into it:
Max. Depth: 31 Feet
Surface Acres: 253
Interesting factoid: Duck Lake was presumably named for an abundance of waterfowl. Note that the United States Geological Survey officially recognizes 161 different lakes with this name in the United States, including thirty in Michigan alone. There is even another "Duck Lake" in Oakland County, in Oxford Township.
