Tree Point Light is an important aid to navigation on the Inside Passage to Alaska marking the entrance to Revillagigedo Channel and to alert mariners of the hazardous Lord Rocks. The channel extends about 35 miles (56 km) northwest from Dixon Entrance and is located 7 miles (11 km) north of the Canadian Border between the Alaska mainland and Revillagigedo, Duke, and Annette Islands.
The original octagonal wooden lighthouse was built in 1903. This was replaced with a new art deco lighthouse built of reinforced concrete in 1933. The station had three, six-room frame dwellings and a schoolhouse located behind a tree-covered hill for protection from ocean winds. A narrow gauge tramway and boardwalk ran 200 yards (183 m) from the tower to the dwellings and then continued on for another .25 miles (.4 km) to the boathouse and hoisting boom, located on a small cove south of the lighthouse. To provide drinking water, a 2 miles long (3.2 km) pipeline linked a large cistern near the dwellings to a lake in the nearby hills. Read more here and here.
