1951 Map of Iliamna A-1 and A-2

About this map

Katmai National Monument dominates the southwestern corner of this coastal Alaska survey, defined by its approximate National Monument Boundary. The landscape is a transition from the marshy outlets of the Douglas River to the open waters of Kamishak Bay and Cook Inlet. Hydrographic data compiled in the early 1950s highlights the treacherous maritime environment, featuring soundings that reveal underwater topography near Augustine Rocks and a vast Tidal Flat along the shoreline. This area remains largely undeveloped, focused on the natural boundary between the protected monument land and the sea, with Shaw Island marking a solitary landmass in the southeastern waters. The lack of roads or trails emphasizes the preservation of this remote wilderness area as it existed during the mid-century mapping effort.
