• The town of Stonesport is inland and actually on Grand Lake, south and a little west of Presque Isle.

• The coordinates you have are a little rough, going only to 2 digits right of the decimal. Streets & Trips puts them in Lake Huron, on a line roughly equal to the south end of Long Lake (the 2nd/southern lake of the two lakes just below Presque Isle). This is about 6 miles off-shore, and about 3.25 miles SE of Middle Island.

• I have a light list of Michigan Lights, listing 193 lights - lights we all know, minor aids, lights on the outhouse, all sorts of lights except one names Stoneport or with those coordinates.

• The books I would consider as knowledgeable concerning GL lights have no listing for this light.

Personally I would skip this one (if it really exists) and concentrate on the many great lights along the Lake Huron coast. Presque Isle alone has 2 lighthouses and a pair of range lights.
