Other evidence for human occupation dating back as much as 14.5 kya (14,500 years ago) is emerging from Paisley Caves in south-central Oregon. The coastal migration hypothesis has been bolstered by findings such as the report that the sediments in the Port Eliza Cave on Vancouver Island indicate the possibility of survivable climate as far back as 16 kya (16,000 years ago) in the area, while the continental ice sheets were nearing their maximum extent. The Pacific Coast is seen by some scholars as a major coastal migration route in the settlement of the Americas by late Pleistocene peoples moving from northeast Asia into the Americas. The Pacific Northwest has been occupied by a diverse array of indigenous peoples for millennia. See also: Indigenous peoples of the Pacific Northwest Coast and Indigenous peoples of the Northwest Plateau Sometimes, the Pacific Northwest is defined as being the Northwestern United States specifically, excluding Canada. ĭefinitions based on the historic Oregon Country reach east to the Continental Divide, thus including all of western Montana and western Wyoming. states of Alaska and parts of the states of California, Montana, and Wyoming, and the Canadian territory of Yukon. īroader definitions of the region have included the U.S. states of Oregon, Washington, Idaho, and sometimes the Canadian province of British Columbia. The most common conception includes the U.S. (3) The labeled states and provinces include Washington, Idaho, Oregon and British Columbia.ĭefinitions of the 'Pacific Northwest' region vary, and even Pacific Northwesterners do not agree on the exact boundary.

Definition None of the multiple possible definitions of the Pacific Northwest is universally accepted. 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'. 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. 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. The region's largest metropolitan areas are Greater Seattle, Washington, with 4 million people Metro Vancouver, British Columbia, with 2.84 million people and Greater Portland, Oregon, with 2.5 million people. The region is sometimes referred to as Cascadia, which, depending on the borders, may or may not be the same thing as the Pacific Northwest.

The term 'Pacific Northwest' should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) or the Northwest Territories of Canada.

The Northwest Coast is the coastal region of the Pacific Northwest, and the Northwest Plateau (also commonly known as ' the Interior' in British Columbia, is the inland region. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, culture, geography, society, ecosystems, and other factors. Other conceptions may be limited to the coastal areas west of the Cascade and Coast mountains. Some broader conceptions reach north into Alaska and Yukon, south into northern California, and east into western Montana. states of Oregon, Washington, and Idaho, and sometimes the Canadian province of British Columbia.

Though no official boundary exists, the most common conception includes the U.S. The Pacific Northwest ( PNW), sometimes referred to as Cascadia, 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.
