san juan island national historical park

 The Pig War was a confrontation in 1859 between the United States and the United Kingdom over the British–U.S. border in the San Juan Islands, between Vancouver Island (present-day Canada) and the Washington Territory (present-day State of Washington). The Pig War, so called because it was triggered by the shooting of a pig, is also called the Pig Episode, the Pig and Potato War, the San Juan Boundary Dispute, and the Northwestern Boundary Dispute. Despite being referred to as a "war", there were no human casualties on either side, only a pig. 

 The English Camp site is on Garrison Bay on the island's northwestern shore. Today the Union Jack still flies there, being raised and lowered daily by park rangers, making it one of the very few places without diplomatic status where US government employees regularly hoist the flag of another country. Surviving buildings from the British occupation include a commissary, barracks, blockhouse, and hospital; the latter building was one that was sold and moved from the site, but was later acquired by the park and returned. 

 The American Camp site is on San Juan Island's southernmost peninsula, and partially overlaps the original Hudson's Bay Company farm. The park property also includes the original site of San Juan village on the north shore of the peninsula, which was abandoned after the dispute ended and was entirely burned in 1890. The camp site includes three surviving buildings from the American military occupation: two officers' quarters, and the house and working quarters of the camp laundress. 

  The park encompasses 2,146 acres, divided between two sites American Camp on the south end of San Juan Island and English Camp on northwest side of the island. Entry to both areas is free, and both include visitor centers. American Camp has three mapped hiking trails, including one to the summit of Mount Finlayson. English Camp includes the Bell Point Trail, Young Hill Trail and Mitchell Hill Trail Network. American Camp includes South Beach on the Strait of Juan De Fuca, with views of the Olympic Mountains, and 4 July Beach on Griffin Bay. Both English and American Camps have kayak launches.
