Boundary Pass

Boundary Pass is a strait that runs for about 23 kilometres (12 nmi) along the boundary between the U.S. state of Washington and the Canadian province of British Columbia. It connects Haro Strait to the south with the Strait of Georgia to the north.

Boundary Pass, along with Haro Strait, connects the Strait of Juan de Fuca and the Strait of Georgia along the international boundary between the United States and Canada. This map follows the USGS definitions. Major islands are named.

The USGS defines its northern boundary as a line extending from East Point on Saturna Island to Alden Point on Patos Island. Its southeastern boundary is a line from Alden Point on Patos Island to Point Hammond on Waldron Island then from Sandy Point on Waldron Island to Charles Point on Stuart Island. Its southwestern boundary is a line connecting Turn Point on Stuart Island to Point Fairfax on Moresby Island. Its western boundary is a line running from Pelorus Point on Moresby Island to Wallace Point on North Pender Island then to Tilly Point on South Pender Island then from Teece Point on South Pender Island to Taylor Point on Saturna Island.[1]
