So the British sided with the Americans and the current border reflects the American claim What were the differences between this and the Canadian claim  Unsigned   Actually the current boundary does not reflect the maximal US claim  Ill try to trype in some more info     The British didnt exactly side with the Americans the border settlement was an arbitration the Kaiser again IIRC as it had been with his father at the end of the San Juans Dispute  The British backed down because of threats by TE Roosevelt that he would invade and annex British Columbia if he didnt get his way  The main difference between the British hard position and the way things are now is that under the British terms thet Yukon Ports  Skagway and Haines and Dyea etc would have been British ie part of British Columbia  Canada didnt have a say in it other than consulting London British North American Canadian foreign affairs were still in Londons bailiwick at that time until  or  or something  As it is under the treaty the site of Forts Stikine and Taku should be within British Columbia and in fact the mouths of the Stikine and Taku should be but theyve silted in a few miles downstream since the treaty was signed the border hasnt been revised to reflect that obviously not even though its in the language same thing with the missurvey of the th Parallel thats not going to get corrected either  There are two sticking points remaining in the Alaska Boundary Settlement  One is that the treaty stipulates that the western shoreline of the Portland Canal is the boundary US maps continue to show midchannel  Similarly with the AB Line which is between Point A and Point B on the north side of the Dixon Entrance US maps show the boundary as being midDixon Entrance and the USAlaska have even issued oildrillingexploration permits on their side of that line  Same kind of fudgeup with the Oregon Treaty during the Salmon War of the mids Canadian commercial vessels whale watching boats were busted by US Coast Guard in the area of the San Juans but the treaty is very clear that ALL commercial vessels south of the th Parallel are to be unhindered that would even include in Rosario Strait far from the current border in the Haro Strait during the same kafuffle Sen Slade Gorton StateSen in Washington invoked the treaty to demand free passage through the Johnstone Strait for American fishing vessels nothing of the kind is guaranteed in the Oregon Treaty or for that matter in the Alaska treaty either and called on the US Navy to enforce the international waterway which is all of a mile wide in spots  Thing is it was the US who passed legislation that attacked nonAmerican ships using this route ie the act that makes it so that preference is given to vessels sailing from American port to American port over those from a foreign port to an American port this act was passed specifically to route the Yukon shipping trade through Seattle over Vancouver even though it was CanadianBritish waters that the route traversed   Further Thoughts  Just considering the opening statements the treaty was actually between the British Empire with the Dominion of Canada as a signatory party IIRC BC was not involved in the actual signing  And just as aside the phrasing of the second condition of the treaty cited  Whenever the summit of the mountains shall be at a distance of more than ten marine leagues from the ocean the limit shall be formed by a line parallel to the winding of the coast and which shall never exceed the distance of ten marine leagues therefrom  is completely bizarre for anybody whos ever actually looked at a map of the coastline  The negotiators were in London and Washington and Ottawa far away with only the dimmest idea of where they were talking about  Much the same as the Oregon Treaty only worse there the deepest channel seemed at least a bit logical even though they didnt note the issues on the map with Point Roberts and the Gulf IslandsSan Juans which make that border a bit of an absurdity which so is the th Parallel from the Rockies westthat aside the Alaska treaty issue cited is utterly bizarre the Alaskan coast is a ragged array of inlets and bays pierced by several large rivers  There is no crest of the mountains for one thing  other than crowsflightdrawn lines from high peak to high peak which i
