Mount Vancouver is one of the highest summits in North America, an imposing icy ridge in the Saint Elias Mountains. There is some confusion as to the elevation and peak names on this mountain, complicated by its location on the Canada-USA border.
The mountain has three summits on a north-south trending crest. The southern summit is on the international border, and is sometimes called Good Neighbor Peak in honor of long-standing lack of hostilities along the longest border in the world. This south summit is also Boundary Peak 181, as per the boundary survey.
The consensus among climbers who have summited this remote and rarely-climbed peak is that the northern summit, entirely in the Yukon, is the highest. However, there is serious disagreement over the elevations.
The U.S. Geological Survey says that the south summit (Good Neighbor) is 15,979'/4870m, while the Canadian maps show it as a closed contour with an elevation of between 4740-4760 meters (15,551-15,617'), a difference of over 100 meters. The Canadians give the northern summit an elevation of 4812 m, lower than the US elevation for the southern summit.
Since the USGS does not give elevations for the middle and northern summits (both entirely in Canada), this site uses the Canadian elevations for all three summits so that the values are at least consistent.
