History


Cape Hinchinbrook Lightstation, 1948
Cape Hinchinbrook Lightstation, 1948

The Cape Hinchinbrook Lighthouse was first established in 1910 to mark the entrance to Prince William Sound. Congress authorized the construction of a lighthouse at this point in 1906 appropriating $125,000 for its construction. However, the full amount was not authorized in one lump sum. The money was appropriated over a number of years with $25,000 in 1906, $50,000 in 1907 and the rest in 1908. As a result, construction did not begin until 1909. In the winter of 1909 a temporary fixed white light was established on the second story of the building under construction. Due to the earthquakes in 1927 and 1928, which caused instability in the cliff around the lighthouse, it was felt a new light should be built on solid rock. The new 67-foot (20 m) octagonal tower was completed in 1934. The lighthouse was automated in 1974 and a solar-powered Vega lens was installed. The original third order Fresnel lens is on display at the Valdez Museum and Historical Archive in Valdez, Alaska.

It was listed on the National Register of Historic Places as Cape Hinchinbrook Light Station in 2005. The listing was for a historic district including two contributing buildings, three contributing structure, one contributing site, and three contributing objects.[3][4]
