About The Sisters Lighthouse
A 17-meter square skeletal steel tower stands on an island in Icy Strait. This structure carries an aerobeacon and emits a white flash every four seconds. The island is located in the center of Icy Strait, a 40-mile passage connecting the Lynn Canal to the Pacific Ocean near Cape Spencer. The site is open to the public, but the tower itself remains closed. The nearest port is Hoonah, 7.2 kilometers away.
Why it matters: This light is critical for safe passage through Icy Strait, a key waterway for vessels navigating between the Lynn Canal and the Pacific Ocean. Its unique design as a square skeletal tower carrying an FAA aerobeacon serves both maritime and aviation needs.
