In short: Spanning 96 miles, this vital Pacific outlet connects the Salish Sea to the open ocean. While named for a Greek navigator who allegedly sailed the region in 1592, historians debate whether he ever existed or if his story was a clever ruse to extract money from the English government.

The Strait of Juan de Fuca serves as the primary gateway between the Pacific Ocean and the Salish Sea. It stretches between Vancouver Island, British Columbia, and the Olympic Peninsula in Washington, with the international boundary running down its center. While the strait is officially recognized by this name, its origins remain shrouded in historical uncertainty. It was named in 1787 by fur trader Charles William Barkley, though some sources suggest John Meares attempted to claim credit for the naming in 1788.

The namesake, Juan de Fuca, was a Greek navigator who purportedly explored the region in 1592. However, a 2003 thesis by Samuel Bawlf argues that Fuca’s account was a complete fabrication designed to secure funding. Bawlf suggests that Francis Drake may have been the first European to sight the strait during his 1579 expedition, with Fuca’s story potentially originating from a pilot named Morera who served under Drake. This debate highlights the complex history of early Pacific exploration and the influence of leaked geographical intelligence on early maps.

Beyond its history, the strait is a dynamic ecological corridor. It hosts resident killer whales and serves as a vital rest stop for migrating gray whales, which socialize with local populations to form new bloodlines. The strait also experiences significant climatic variation, with rainfall ranging from over 100 inches at its western end to as little as 16 inches near Sequim. While the maritime boundary within the strait is settled, a dispute persists regarding the seaward boundary extending 200 nautical miles west, complicated by conflicting legal principles of equidistance and natural prolongation.
