San Juan Island National Historical Park

Rank: 170

Park Description

San Juan Island is well known for splendid vistas, saltwater shore, quiet woodlands, orca whales and one of the last remaining native prairies in the Puget Sound/Northern Straits region. But it was also here in 1859 that the United States and Great Britain nearly went to war over possession of the island, the crisis ignited by the death of a pig.
