The sun is setting here on the west coast of Washington state"s rugged Olympic Peninsula, where more than 3,000 square miles of marine waters are protected as part of the Olympic Coast National Marine Sanctuary. Wondering where exactly we are? Look at a map of the United States and draw your finger up the West Coast until it ends where the Strait of Juan de Fuca meets the Pacific Ocean. Those final 135 miles of shoreline form the landward boundary of the sanctuary, which also extends seaward 25 to 50 miles.
