[edit] Guessing

• The date on which the lighthouse was moved is variously reported as 1917, 1918 or 1919 by the sources.
• I do not know if the height figure is for the light source, or of the top of the tower.
• I got the height above sea level by adding 82 ft to 579 ft, a commonly given level of Lake Michican above sea level, so this figure could well be off a few feet.
• I derived the coordinates from google and yahoo maps, and I could be off by as much as an arc-second--my figure should not be used for navigation. Speciate 21:41, 9 May 2007 (UTC)

[edit] Disposition of the original Third Order Fresnel lens

I note that Terry Pepper, Seeing the Light, writes that the original lens is still in place. However, I went with the information in the National Park Service, Maritime Heritage Program, Inventory of Historic Lights which says it was moved to Cabrillo National Monument. While I have no idea which is true, Pepper says he's never personally visited this light, and the National Park Service would seem to be in the best position to know about a move of the lens, I think. The Coast Guard site lacks any specifics on this lens. I would add that the National Parks Inventory also says in the Grosse Point Light article that only three original Fresnel lenses remain in place on the Great Lakes. http://www.nps.gov/history/maritime/nhl/grossept.htm I would add that this statement is wrong, as I personally have seen and know that the 3.5 order Fresnel lens is still in place at Sturgeon Point Light, and that isn't cited in their article. So one must also 'take with a grain of salt' the representations made in the National Park Service inventory. However, if the article intends to limit consideration to only lenses that have been in place since day one at a particular light, then it would be correct, as Sturgeon Point's lens was replaced in the 1880s, and a larger lens put in.7&6=thirteen (talk) 12:04, 16 May 2008 (UTC) Stan
