 The Bridge River Country has also been referred to as the West Cariboo, but is not considered to be in the Cariboo by its residents.Many urban residents are under the impression that the Bridge River Country is part of the Chilcotin because of the "South Chilcotin" name for the Spruce Lake Protected Area, but this is incorrect.The Southern Interior roughly falls south of the Thompson River and Shuswap Country (corresponding mostly to the post-Oregon Treaty remainder of the old, original, Hudson's Bay Company Columbia District).
