GPS Recreational Reference Points at Area Boat Launches
 are provided by the Northeast Chapter of the Wisconsin Society of Land Surveyors.
These are conveniently located very close to boat launches so that boaters can quickly check

The monuments have brass circular surfaces roughly 4 inches in diameter encased in an eight inch diameter concrete cylinder that is buried in the ground so that the brass surface is just below the level of the surrounding landscape.  The Green Bay and the Sturgeon Bay ones do not show the coordinates.
