At the entrance to Cross Sound.
Cape Spencer Lighthouse, Alaska, is a primary light, fog signal, and radiobeacon station, marking the northerly entrance from the Pacific Ocean into the inside passages of southeastern Alaska. It is on a route much frequented by vessels seeking to avoid the often stormy outside passage. Cape Spencer is one of the most isolated of Alaskan lighthouses, where the keepers must go 20 miles for their mail, and where the nearest town of any size is 150 miles away. The station was commissioned in 1925, and is fitted with the most modern types of signalling equipment. From the top of the tower is shown a light of 500,000 candlepower, and in time of fog a diaphone fog signal is sounded at regular intervals. The radiobeacon, established in 1926, and the first radiobeacon in Alaska, is of high power, with a range of 200 miles and more at sea. The station buildings are of reinforced concrete construction.

SCOTCH CAP LIGHTHOUSE, UNIMAK ISLAND
Scotch Cap Light was built in 1903. It consisted of a wood tower on an octagonal wood building 45 feet high and was 90 feet above the sea. It was located on the southwest end of Unimak Island and on the east side of the Unimak Pass into the Bering Sea. It was the first station established on the outside coast of Alaska. Prior to the introduction of the helicopter, access to the stations was so difficult that it was impractical to arrange for leave of absence in the ordinary way. Instead each keeper got one full year off in each 4 years of service. Coast Guard enlisted personnel now man this isolated unit on a rotating one year tour of duty.
During an earthquake and tidal wave of April 1, 1946, Scotch Cap Lighthouse slid into the sea and all five persons on the station were lost.
A temporary unwatched light was established in 1946, consisting of a small white house exhibiting a light of 300 candlepower maintaining the former station characteristic of flashing white every 15 seconds, flash 3 seconds, eclipse 12 seconds. A radiobeacon was temporarily reestablished at the radio direction finder station.
The new permanent structure was completed in the early part of 1950 and the temporary light and radiobeacon discontinued. The new station consists of a 800,000 candlepower light exhibited from a white rectangular building with flat roof, a diaphone fog signal, and a radiobeacon. [(1)] [(2)]
