Cape Hinchinbrook Light, Maritime navigation aid in Valdez-Cordova Census Area, United States.
Cape Hinchinbrook Light is an octagonal concrete tower on Hinchinbrook Island marking the entrance to Prince William Sound. The white structure with black lantern room rises about 20 meters and displays Art Deco design elements.
The original tower was authorized by Congress and construction began in 1909, with operations starting in 1910. The current reinforced concrete structure was built in 1934 after earthquakes in 1927 and 1928 damaged the original building.
The light tower takes its name from the nearby cape and island, serving as a recognizable reference point for mariners across generations. Today it remains a familiar landmark that guides vessels into the waters of Prince William Sound.
The lighthouse operates on solar power and transmits a white light signal every 15 seconds visible for about 19 nautical miles. The island location means visitors must travel by boat and access is limited by weather conditions.
The original third-order Fresnel lens that once operated here is now on display at the Valdez Museum, showing how navigation technology evolved in Alaska. This lens was once the heart of the light tower and enabled ships to spot the coastline from far away.
