1955 Map of Prince Rupert D-4

About this map

Duke Island dominates this mid-century hydrographic and topographic survey, situated within the southern reaches of the Tongass National Forest. The map documents a maritime landscape defined by protected waters and navigational hazards, from the southern tip at Cape Northumberland to the northern shelter of Pond Bay. Significant marine features include Ray Anchorage and Judd Hbr, which provided essential refuge for vessels traversing the Revillagigedo Channel. The terrain is characterized by low-lying islands and isolated heights such as Duke Hill, providing a clear record of the shoreline before modern development. Smaller landmasses like Dog Island, Kelp Island, and the Sister Islands are meticulously charted alongside sounding data, offering researchers an exact look at the coastal geography of the Alexander Archipelago during the 1950s.
