1951 Map of Afognak D-4

About this map

Katmai National Monument defines the western coast of this maritime study, where the Alaskan mainland meets the churning waters of the North Pacific. The prominent headland of Cape Douglas anchors the shoreline, surrounded by the hazardous waters of Douglas Reef to the south and the sheltered indentation of Sukoi Bay to the north. This mid-century hydrographic and topographic survey provides a detailed record of the soundings and bathymetry where Cook Inlet transitions into the broader Shelikof Strait. An approximate National Monument Boundary is charted through these waters, illustrating the protected marine and coastal reaches during a period when aerial photography was first being used to refine the rugged coastline of the Alaska-Third Judicial Division.
