About this map

Hinchinbrook Island and the northern tip of Montague Island frame the vital maritime passage of the Hinchinbrook Entrance in this mid-century hydrographic study. The map focuses heavily on the navigation and safety infrastructure guarding the approach to Prince William Sound, centered on the Hinchinbrook Lighthouse Reserve. Here, a Lighthouse, Radio Tower, and radio station provide essential guidance for vessels transitioning from the open waters of the Pacific Ocean and the Gulf of Alaska into the inner sounds.
