Stump the German

[Eva Elisabeth]

First of all thanks to all participants!

Kudos, Roger, you nailed it. (Sorry, initially I totally forgot Canada is a federal parliamentary constitutional monarchy, the monarch being Elizabeth II...). And Wild Bill - it's indeed a sea boundary, the Lincoln Sea.

Just to visualize - this (green) all is Denmark:
   
The Lincoln Sea is a body of water in the Arctic Ocean, stretching from Cape Columbia, Canada, in the west to Cape Morris Jesup, Greenland, in the east. The northern limit is defined as the great circle line between those two headlands. The broken blue lines indicate 200-nautical-mile zones:
       
1) Lincoln Sea; 2) Nares Strait; 3) Baffin Bay 4) Davis Strait ; 5) Labrador Sea

The sea was named after Robert Todd Lincoln, then United States Secretary of War, on Adolphus W. Greely's 1881–1884 Arctic expedition.

The Lincoln Sea is covered with sea ice throughout the year, the thickest sea ice in the Arctic Ocean. Alert, the northernmost station of Canada, is the only populated place on the shore of the Lincoln Sea, and the most northern populated place in the world at all.

A disagreement on the maritime boundary in the Lincoln Sea (i.e. on a 200-square-kilometre section) emerged after 1973 when Canada and Denmark signed a treaty establishing the offshore boundary north of Canada's Ellesmere Island and Greenland that left portions of it undefined. On Nov.28, 2012, both countries finally reached a tentative agreement on the Lincoln Sea boundary.

Laurie and Roger, you win a trip to celebrate July 4 at the Lincoln Log Cabin Museum in Rebild, Denmark:

I learned of the existence of this place from Dr. Steers' new book, and this is what he replied upon my inquiry:
"In Rebild, Denmark there is a Lincoln Log Cabin Museum that houses a Lincoln exhibit and bronze plaque of Lincoln. Each year on May 30 and July 4 ceremonies are held there. In 1962 Richard Nixon attended and gave a speech. 40,000 people attended. The people claim that the largest crowds that gather on July 4 are not in America, but in Rebild, Denmark."

He also sent this photo of the plaque (thanks, Dr. Steers!):
   
...and I found a newspaper article about Nixon's attendance. It's a pdf file, I hope Roger will kindly help to make it accessible...
