Cascadia, a term that derives from the Cascade Range, in OTL usually refers to the Pacific Northwest, but there are other locations known as Cascadia. Cascadia is also the proposed name for an independent nation that would be created by the combination of British Columbia, Oregon, and Washington through the secession from their respective federal governments. Other definitions of Cascadia include a large bioregion extending from north to south from the tip of southern Alaska down into Northern California, and encompasses to the east parts of Alberta, the Yukon, Idaho and Western Montana. The boundaries of the proposed government could incorporate those of the existing provinces and states.
