message: According to the Eastern Hemisphere article, the Eastern Hemisphere is bounded by the Prime Meridian and the International Date Line, not the 180th Meridian;  this would mean Semisoposhnoi is not in the Eastern Hemisphere, and is therefore not a candidate for the most easterly point in North America.

replies: text: The Eastern Hemisphere article was simply wrong; I've corrected it. A hemisphere is "A half of a sphere bounded by a great circle" or "Either the northern or southern half of the earth as divided by the equator or the eastern or western half as divided by a meridian" or "half of the terrestrial globe" (Dictionary.com. The American Heritage® Dictionary of the English Language, Fourth Edition. Houghton Mifflin Company, 2004, or WordNet® 3.0. Princeton University. http://dictionary.reference.com/browse/hemisphere accessed: May 23, 2008). As the Prime Meridian article correctly notes, "The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres." The Western Hemisphere article also correctly states, "The Western Hemisphere, also Western hemisphere[1] or western hemisphere,[2] is a geographical term for the half of the Earth that lies west of the Prime Meridian (which crosses Greenwich in London, England, United Kingdom), the other half being the eastern hemisphere."  All longitudes east of zero degrees and west of 180 degrees are labeled "East".  Semisopochnoi Island, as the article states, is at 179 degrees East and therefore is at least arguably in the eastern hemisphere. This and related articles use terms such as "arguably" to qualify claims of being the easternmost point and as such should remain. Station1 (talk) 06:01, 24 May 2008 (UTC)
replies: text:  I'd argue that, while in the Eastern Hemisphere, Semisoposhnoi is not in North America.  It is, in fact, closer to the Asian mainland.  Of course, all of this is original research.  Don't Be Evil (talk) 15:31, 6 January 2011 (UTC)
thread_title:  Not in Eastern Hemisphere 

message: "Greenland is not politically a part of North America."  What does this even mean?  The Greenland article points out that it is a part of the NA continent... and I do see the "political" distinction, but what does that mean?  Why is that relevant to discussing the extreme points of the continent?  I am going to remove this sentence.  Someone will probably revert it, so please explain why it belongs.  —Preceding unsigned comment added by 71.191.196.228 (talk) 03:56, 30 December 2010 (UTC)

message: West and east are rotational directions on the earth. Therefore Alaska lies on the eastern side of Bering straits and Russia on its western side. It is likely that this island is, indeed near the westernmost point of North America.
