America was a steel freighter that was 183' long.  The bow of the ship has ice damage but the middle and stern of the ship are in good shape.  Use caution if penetrating this wreck or any other wreck as silt stirs easily.  The wreck is located in the North Gap of Washington Harbor.

Kamloops was a freighter that was 250' long.  The ship disappeared in a storm in 1927.  The ship was discovered by divers in 1977.  This wreck has been explored by ROV after it was discovered.  The wreck lies in more than 200' of water and is far beyond sport diving limits.
