It was named by English Capt. John Meares after a legendary Greek sailor. There's an actual boundary dispute between the United States and Canada over the western part of the strait.
The Strait of Georgia lies between Vancouver Island and mainland British Columbia. It's about 150 miles long and from 11.5 to 34 miles wide. There are several inhabited islands in the strait.
British Columbia's lakes tend to be long and narrow, and many of them are just a wider and deeper tributaries of the Columbia River.

The Columbia River is the largest river in the Pacific Northwest. It not only flows through British Columbia, where it begins in the Rocky Mountains, but flows through Washington and into Oregon where, after a journey of 1,243 miles, it empties into the Pacific Ocean. It's been a vitally important river for millennia. Its salmon runs have fed generations of people, and its many hydroelectric dams have provided electricity to millions of people.
