SAN JUAN ISLAND N.H.P.
In 1859, the U.S. and Great Britain nearly went to war over possession of San Juan Island due to a crisis ignited by the death of a British-owned pig. Military encampments were made as a response and occupied for 12 years of the Pig War Crisis until the Treaty of Washington was signed. Today,
San Juan Island National Historical Park is known for its splendid vistas, saltwater shores, quiet woodlands, orca whales, and one of the last remaining native prairies in the Puget Sound/Northern Straits region.
