The Pacific Northwest, also referred to as Cascadia, is a region on the west coast of North America. It refers to the northwestern corner of the United States and the southwestern part of Canada. The U.S. states of Washington, Oregon, Idaho and western Montana are in the southern part of the Pacific Northwest. The Canadian province of British Columbia and the southeastern part of the U.S. state of Alaska is in the northern part. The entire region is bordered by the Pacific Ocean to the west.

Historically, the Pacific Northwest had been inhabited by Native Americans. Starting from about 15,000 years ago, Native Americans settled along the coastline and along the major rivers. From the 1500s to the 1700s, Europeans explored the region, beginning with the discovery of Oregon and Washington. In the early 1800s, the famous Lewis and Clark expedition arrived in Washington State. From the 19th century to present day, the region began to become settled. Today, the largest cities in the Northwest include Vancouver, Seattle and Portland.

The rugged mountains of the Northwest consist of the Coast Range, which is nearer the coast, and the Cascade Range. In northern Washington, the Cascade Range is called the North Cascades. In British Columbia, it is called the Canadian Cascades.^[1] The many rivers of the Northwest result from its wet climate - the mountains trap wet Pacific air, leaving little rain for inland states like Idaho. The rivers once supported large salmon runs, but large power dams have been built on many rivers.

The main language of the Pacific Northwest is English in the United States and Canada, among the Native Americans Chinook Jargon is common. Among the many Asian immigrants, Chinese is being used more in the Northwest.
