The Pacific Northwest (sometimes Cascadia, or simply abbreviated as PNW) is a geographic region in western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east.

The culture of the Pacific Northwest is influenced by the Canada–United States border, which the United States and the United Kingdom established at a time when the region's inhabitants were composed mostly of indigenous peoples. Two sections of the border—one along the 49th parallel south of British Columbia and one between the Alaska Panhandle and northern British Columbia—have left a great impact on the region. According to Canadian historian Ken Coates, the border has not merely influenced the Pacific Northwest—rather, "the region's history and character have been determined by the boundary".

Our multi-leg achievement starts at Astoria Rgnl in the state of Oregon, flying into Washington state, entering the province of British Columbia and completing the first part of this achievement at Alert BaY.
