Original pen & ink rendering. Cape Disappointment is the first in my series of Washington State lighthouses. The lighthouse is owned by the Coast Guard, and the grounds are open to the public, although the tower is closed. The lighthouse has continued to watch over the entrance of the Columbia River since it was first lit on October 15, 1856. It stands 53 feet tall with a focal plane 220 feet above sea. Its black horizontal stripe was added later to distinguish it from North Head Lighthouse located just two miles north.
