Cape Spencer Light

Cape Spencer Light is a white concrete tower with a black gallery and red roof situated on a small islet at the entrance to Cross Sound. The station is equipped with a solar-powered Vega optic that transmits its signal to guide vessels moving between the Outside Passage and Inside Passage routes.

The lighthouse was built in 1925 following Congressional funding allocated in 1912 specifically for Alaska navigation aids. This construction was part of a broader effort to improve safety for increasing ship traffic through Alaskan waters.

The lighthouse became part of the National Register of Historic Places in 1975, reflecting its role in guiding maritime traffic along this remote Alaskan waterway. Ships passing through these waters rely on its light as a navigation landmark.

The lighthouse sits on an islet surrounded by steep cliffs that make landing difficult. Visitors should come prepared for remote and exposed conditions, as boat access depends on favorable sea conditions.

Four lighthouse operators once maintained constant radio communication from this remote outpost. Supplies had to be hoisted by crane due to the surrounding cliffs, creating a unique logistical puzzle that defined daily life here.
