Of course, the problem is that there're more than one sensible way to define "easternmost". The way I'd define it, the point in *Maine* would be the easternmost point measured from the "prime meridian", instead of the web site's claim of the Alaska point. (My definition being that one point is further east than another if you have to travel further east to get there, starting from the reference longitude. This would mean that there is actually no easternmost point of the U.S. measured relative to any reference longitude which passes through the U.S., if you think about it. Hint: the range of the longitude function on the set of U.S. geographical points would be a half-open interval, open on the right. Also, another problem would be if the boundary of the U.S. were not wholly contained in the U.S. -- e.g., if the points of the U.S. formed an open set in the usual R^3-subspace topology on the globe. In this case, there might not be an easternmost point of the U.S. measured from ANY reference longitude.)
