Antarctic Connection Exclusive!
Fashioned from pewter, the 2010 U.S. Geographical Marker highlights the largest neutrino detector in the world which is in operation at the South Pole. The top of the array; better known as Icecube, is a 10 meter telescope and below are strings of detector arrays.
Engraved around the edge is the text, "Science at Latitude 90* South- Geographic South Pole -NSF - January. 1, 2010"
The geographic South Pole sits at 9300 feet (2835m) above sea level. Because the actual South Pole is covered by roughly 9000 feet (2700m) of moving glacial ice the surface mark actually moves approximately 30 feet (10m) annually. Each January 1st the position of 90 degrees south is re-determined and a new unique survey marker is erected.
* Paperweight is 3 1/4 inches in diameter.
* All come with felt tabs on the bottom to keep from scratching surfaces.
