Semiahmoo First Nation

The Semiahmoo Indian Reserve ( SEM-ee-AH-moo) is a 129.1-hectare (320 acre) Indian reserve in the Lower Mainland, British Columbia, located on Semiahmoo Bay between the City of White Rock and Peace Arch Park, which sits astride the international boundary with Washington state. The reserve is under the administration of the Semiahmoo First Nation, which is the band government of the Semiahmoo people, a North Straits Salish-speaking subgroup of the Coast Salish. Currently the people of Semiahmoo's chief is Harley Chappell (since 2017). The Semiahmoo Reserve was established by the Canadian government in 1887.

Peace Arch Park is an international park consisting of Peace Arch Historical State Park in Washington, United States and Peace Arch Provincial Park in British Columbia, Canada. The park straddles the international boundary between the two countries at the extreme western end of the main contiguous section of the two countries' land border, between Blaine, Washington, United States, and Surrey, British Columbia, Canada, where it reaches Semiahmoo Bay of the Salish Sea on the continent's Pacific Coast. The park's central feature is the Peace Arch. The park is located at the Peace Arch Border Crossing (also known as the Douglas Border Crossing), where Highway 99 in British Columbia and Interstate 5 in Washington State meet. The park's northern portion is about 9 hectares (22 acres) and is managed by the British Columbia Ministry of Environment. The southern portion is about 20 acres (8.1 ha) and is managed by the Washington State Parks and Recreation Commission.

The Peace Arch (French: Arche de la Paix) is a monument situated near the westernmost point of the Canada–United States border in the contiguous United States, between the communities of Blaine, Washington and Surrey, British Columbia. Construction of the 20.5-meter (67 ft) tall arch was headed by American lawyer Sam Hill and dedicated in September 1921. The Peace Arch commemorates the signing of the Treaty of Ghent in 1814, and symbolizes a long history of peace between the two nations. The monument is built on the exact U.S.–Canada boundary, where Interstate 5 on the U.S. side of the border becomes Highway 99 on the Canadian side, in the grass median between the northbound and southbound lanes. The monument and the surrounding land is part of Peace Arch Park. Within the park is Peace Arch Border Crossing, a major border crossing between Interstate 5 and British Columbia Highway 99.

The Campbell River passes through Surrey and Langley, British Columbia, Canada, entering Semiahmoo Bay at the Semiahmoo Indian Reserve, which lies between the City of White Rock and Peace Arch Park on the international boundary. Originally labelled Campbell Creek in 1917 by the Geographic Board of Canada, it was labelled Tahtaloo on International Boundary Survey sheet 2 (date not cited) (a toponym derived from Tah-tu-lo, the Semiahmoo endonym for their dialect of Straits Salish); variant spellings include Tahla too, Tah-la-loo, and Tah tu lo. It was probably named after Archibald Campbell, US commissioner in the joint negotiations to locate the international boundary 1857–1862, who had his camp at the mouth of the creek. It was identified in the field notes of Joseph Trutch's survey as Semiahmoo Creek in 1859. "Ta’talu" is the name used nowadays by the Semiahmoo First Nation residing in its vicinity.

The Peace Arch Border Crossing is the common name for the Blaine–Douglas crossing which connects the cities of Blaine, Washington and Surrey, British Columbia on the Canada–United States border.

MV Plover is an 11-ton, 17-passenger ferry in Whatcom County, Washington, built in 1944, listed on the National Register of Historic Places in 1997. She is owned by the City of Blaine, Washington and operated by the nonprofit Drayton Harbor Maritime. She originally ferried workers from Blaine to the Alaska Packers' Association cannery at Semiahmoo Spit (now the site of Semiahmoo Resort), carrying out this function until 1964. She was restored by volunteers of Whatcom Maritime Historical Society, and now carries passengers during the summer months from the Blaine harbor dock across Drayton Harbor to the resort dock. At approximately 1 kilometer, this is claimed to be the shortest ferry run in Washington. She is the second oldest operating foot passenger ferry in Washington, next to Kitsap Transit's Carlisle II which was built in Bellingham 27 years earlier, in 1917.In 1998, the Plover restoration was recognized by the Washington State Department of Archaeology and Historic Preservation as demonstrating "the best of preservation practice" with a Valerie Sivinski Award for Outstanding Achievement in Historic Preservation Rehabilitation Projects.
